headlight motor grinding
when I shut my headlights off on my 1999 3.8L auto, the headlight motors grind gears for 3-4 seconds after the lights retract. this is very loud, and cant be good. how do I fix this?

The Pontiac Firebird isn't really made for more than one person. With a tiny rear seat and little regard for the front passenger, it's all about the driving experience. And once you're behind its wheel, who gives a hoot about anyone else inside or outside the car? The 1999 Firebird is fresh off a redesign from the previous year, so few changes were in store. It got a bigger gas tank and a new traction control option across the line. The V8 models also got a Torsen limited slip differential. To celebrate its 30th year, a special anniversary edition white Firebird with blue stripes was issued, with an airbrushed image of Knight Rider's David Hasselhoff on the hood. OK, I'm kidding about the Hoff part.
The 1999 Firebird came in both coupe and convertible forms. Base model featured a 3.8-liter, 200-hp V6, while the Formula and Trans Am carried the new LS1 V8 engine rated at 305-hp. With the WS-6 performance package, that rating went up to 320-hp and added dual exhaust tips, alloy wheels, and hood scoops. The LS1 harkened back to the muscle car days of yore, producing one of the fastest Firebirds in Pontiac history.
The LS1 V8 was fierce and fun, say owners, though V6 drivers were more than satisfied with their engine performance. Aggressive styling, tight cornering, and overall muscle car action are the Firebird's biggest selling points, along with its affordable price tag. A backseat that would make Mini-Me feel claustrophobic, poor traction in bad weather, and problems with the ABS system were common complaints.

If i was to acquire a 427 cubic inch motor (6.9 almost 7 liters) would it be able to fit inside a 1999 Pontiac Firebird? obviously if it did id have to change some things out such as the tie-rods and rear end but i need to make sure it would fit first and i don't feel like spending $15,500 just for it not to fit. It's also a base model so id have to swap the hood possibly go to a ws6 hood or do a hood cutout and id have to make sure that it isnt too loud so i dont get pulled over i plan on making it basically a street legal drag car without slicks
The motor and switch have been replaced on the driver's side. It then worked for awhile but won't work again at times. I have noticed that this problem only occurs when the clock light on the dash goes out. Could this be an ignition problem? The last time it happened, it lasted for a month and then the clock light came on at start up and the windows worked.
Can a firebird/Camaro owner '99-'02 please tell me where I can snag a QUALITY dashmat? Impossible to confirm by looking at online pictures. ALSO, is there a product that will repair cracking on dash/door panels? Much grass, Stevey
