Ya know....
as with anything that says "universal" I always find that its NOT !
Just because I do know that windows come in different shapes/sizes and different stresses apply to each, so the window regulators are designed for each application, I would think. That being said, it does'nt make sense that a unique car like a corvette would accept generic parts for even the most common subsystems like regulators.
Still might be the real deal.....I know they'll take it back and order the right one if it don;t work. Its Bound to be cheaper than Ecklers:ugh or the other catalog stores. Give it a shot. If there is $3 to be saved somehow, thats almost 1/2 gal:eyerole of gasoline or about 10 miles of city driving !
