Ok so apparently the 99 cavalier convertible takes a special kind of window regulator that noone has. I need to know if this is in fact interchangeable with the 2 door coupe or if it has to be specifically for the convertible. Also anyone that knows where to find one please let me know because none of the yards have them, autozone and oreilly's can neither one even order one, and my window is down about an inch and a half and wont move(which makes for a wet ass) Any help would be greatly appreciated, until i hear something i guess i will just go buy a car cover!!

GMPD lists the convertible regulators as different part numbers than the coupe/sedan regulators. As to whether coupe ones fit, about all I can suggest is get one from the salvage and compare them. I don't see why they should be much different, maybe a bit longer or something to that effect.

if you just need a motor then they are the same
