500$ you stole that car. Sadly because they are on the rare side they may be big $$$ check some local junkyards and swap meets. go to a car show or two and ask some of the guys with similar cars where to get parts. Some of them have a parts stash of their own and would be more than willing to help.


the only part that i really need to replace are the front and rear transmission seals. but its my first car. i bought it from my ex girlfriends dad. he told me he wanted $1000 for it but when i took him the down payment he told me $500 so i still owe him $200. but my cousin is going to help me with the car and fixing it up. it starts and i put tranny fluid in and it backed up 8-9 feet then i pulled forward about 5 feet then it stopped. so i got out and jacked it up and seen it had poured all the tranny fluid out of the front seal on to the ground. it sounds really good and its going to look really good. it has a couple of rust spots on the hood and the roof of the car but im going to sand it down and then repaint it a baby blue with a metallic flake and neon green racing stripes with metallic flake


With trans seals, I would go to a transmission shop and have them rebuild it. Manual or auto trans will make a cost difference. It has been a long while since I have heard numbers for rebuilding the trans.

My cousin was going to help me out the seals in and he knows how to but where would i go to get the seals. could i get them at napa. because i live in superior montana and i cant really get and where to go to a transmission shop. but our town is probably five miles long and i dont have a car to get to missoula wich is about 68 miles away from where i live that would be where the only place with a transmission shop. but we have a napa auto parts and thats it.


Napa=No Auto Parts Available It seems every time I go there they do not have what I am looking for. It is worth a shot to go there and try. You could ask for price and availability, for the seals, and for a trans rebuild kit. It may be better to rebuild the whole trans if it has been sitting for awhile as it seem from what you had said.


it has only sat for 2 1/2 years it was being towed behind a uhal and the uhal fliped because of stupidity and the car and uhal where both towed and the owner whent to jail. so i bought it from the owner of the shop that it was taken to witch is my exs dads shop. he put the drive line back in and the car has no title. the people who owned the car and told them that he can keep the car. but my exs dad dont have a licens and so he sold me the car. we are getting a title for abandenment. but the car has only sat for 2and a half years. then i put trani fluid in and the car backed up and moved forward then stoped so i looked under the car and the trani leaked all the fluid. i was told by the shop owner in town that they did the same thing and the same thing happend to them and they didnt want to work on it because it is a ford mustango cobra with a boss 302 engine and he knows absolutly nothing about the car and the engine.


it is a car that is a little on the rare side.


Hey bud, if you have your own debit/credit card, check out They have parts for just about any car, including yours. Your seals range from 1 dollar to 9 dollars, from what I saw. Good luck.


Also, try


so how rare is this kind of car. like i said im only paying 500 for it and it may only be 300 if i have to get the title on it my self. its a good project car. my girlfriends mom just dont want it at the house till i get the title.but if i have to get the title myself then im only paying him 300

I had a 1977 302 powered Mustang II, which was essentially the same as the Cobra. I had the C-4 auto, although you could also get a 4spd. My little guy pulled really hard out of the hole, but after 4000rpms he dropped power fast. I topped mine out at 117. Of course, it did have 180,000 on it at the time. Still ran smooth and quiet, just leaked everywhere. Oh, muffler fell off, +10mph top speed. Talk about restrictive. All in all, I really liked the little bugger, it's just the uni-body was notorious for rusting out and weakening. Some articles about the car. and one for sale$9-600/


How do you spin tires if the transmission is leaking fluid, no fluid =no pressure and no pressure = no torque. If you are 19 and you DO have this car it is best left to someone that knows it well. They are becoming more and more rare. If your going to tear it up sell it. otherwise keep it an i'm all for it. If the front seal is leaking horribly and it has been driven for a while chances are the torque converter is now junk along with the front pump. Mite as well do a rebuild on it.


they found video of the car when my ex girl friends dad got it of him showing the tires spinning. when i got it i had to tow the car then while at my cousins i put trany fluid in and backed it up then pulled forward and then it stopped moving and then i looked under the car and the transmission fluid was on the ground

This mustang II you have,sounds like a keeper..Because of the hot-rod craze,back in the day,ALOT were scrapped,just for their front suspension..The BOSS 302,was discontinued,after the 1970 model,so,it is safe to say,your cobra II,has the conventional 302(5.0)V-8,and C-4 transmission,,Parts are still out there,at local parts stores,for this combination..Good Luck,with your new toy!! These little mustangs,are a blast to drive,and own!

thanks for that info i am now in the situation that the last time i was on i was getting help with the car i dont have the tools or the time anymore to work on my car so i sitting on the conditions to just sell the car there are a few rust spots and i am paying a mechanic to fix the car to where it runs so i can sell it for more then what i could with out it moving and then i am going to pay him off and bet me a truck then sell my f150 thanks guys for all the info and knowledge but i dont have the choice to keep the car no longer i am wanting to start my family with my fiance and i wont have time to do anything with this car after i start and have a kid. im sorry if i disapoint you guys by selling it but i am going to ask one last thing what should i price it at for sale.


Wrong engine, or wrong info, either way you should I.D. what really is in there and what trans. otherwise you have to pull seals and get numbers off them to order parts. There was no boss 302 in that year, call a spade a spade, and a spud a spud. To make it faster to know, do the freeze plugs screw into the water jacket? or not? Then, what is the shape of the trans pan, how many bolts? Talk to your parts people, let them ask or that is the "spinning your wheels" you will experience

Look guys, hate to burst your bubble, but the 1977 mustang was junk. It was based on the pinto platform and had a gutless 302 2bbl wedged between the rails. The "cobra" was $20 of stickers put on at the factory and a couple of pieces of plastic. There was no "boss 302" engine or anything even close to it. It was an interim measure of cobbled together parts until ford could get the new body style out. The best place for this model is the junk yard -- I know. I used to work for the factory.


Dats da fact jack!


Dear Mboyett, you are not going to disappoint anyone. It is not what you said, and we have told you so. I was more disappointed last time I had to flush. Sorry bud. You can still have fun with it all you like.

I owned a 77 Cobra and it will rip the tires even if it is rusted to shit.. If you are interested in selling what you have please feel free to email me.. or anyone else who owns this car.. yes it is unibody.. yes you can say whatever about it.. i still want it.. i will pay cash right now


There's no BOSS engine made in 77, theres a smoggy cobra II. aka, pintostang. after removing all the polluter devices you could salvage something to enjoy, I know I cant breathe with my fist there and pinching my nostrils and neither could that 302 car engine. Or whatever has been put in there. You notice on this thread that whenever the accurate info is brought up, all we have ever heard is confused mismatched impossible perceptions by the vehicle owner? and then no response to any of our questions. obvious troll prank at this point.

I have ALWAYS wanted a mustang, like maybe a 1966. While they are reasonably priced, I still don't have that kind of money. Then my husband's cousin called from KY and wants him to buy me her 1977 cobra II for $3500. Apparently it's in excellent condition, although it's never been "restored." It was her dad's then passed to her. Never driven in winter. It's definitely nothing like a '66. In fact it looks cheap in comparison. After reading some of these comments, I don't husband is an old-time mechanic from the 60s/70s. He knows what he's doing, but do I want to "settle" for this 77 when I really want a 66???

Put a Windsor 357 instead of a 302. There is no BOSS 302 for a 77 Cobra II. The car was made to be really fast if you pull out all the heavy junk that weighed it down as mentioned above. I have never heard it called a smoggy cobra II but you can take the faux intake off and replace it with a working one to get air flow in there. If you tweak the 77 Cobra II the front end has a tendency to lift off the ground going toward the maximum speed. I have seen some wheelie bars on suped up versions. The 66 is a cool car and I would recommend a 68 or 69 if you want the best of the 60s.

go to napa auto parts they have it, this is my 1977 cobra
