how do you replace a power antenna on an 85 caddy fleetwood

The bad of this,you have to remove fender to replace.

It's a simple fix and all it takes is patience. Fender doesn't have to be removed. 1st, Turn wheel all the way to the right. This can be done while car is on the ground. 2nd, loosen 3-4 screws at lower rear bottom of the inner fender which holds the plastic cover. 3rd, once removed, there are 2 screws near the top of the antenna and 1 more near the bottom of the antenna which holds it in place. Once removed, it will fall down and you can then reach inside the fender to work it out. Let me know if this is helpful?

NOT ENOUGH ROOM TO GET YOUR HANDS UP THERE TO GRAB ANYTHING. MUST REMOVE FENDER.
