I have recently come across a parts cars with a salvage certificate that i am interested in buying. The car is a 1987 formula and has louvers on the rear window. After looking the car over, i noticed that the rear "aero" style foam wing is attached to the outside of the louvers as opposed to the glass underneath of them. I have never seen the spoiler attached attached in this fashion. This may be due to the fact that i havent seen many birds with that wing with louvers. My question is, was this car available from the factory with louvers? / and if so are these factory louvers. Any insight/ advise is greatly appreciated. -Bob

 

Factory louvers from GM came in several different versions: the no third brake light; third brake light on the outside of the hatch (1986); third brake light inside the hatch (early 1990's); and even a version to go with the rear wiper option. I'm not aware of any factory version that mounted on the rear wing. JC Whitney and a number of different vendors sold a variety aftermarket versons years ago. What your're describing may be one of these. A picture would help. The GM factory louvers all mount to the glass and the hatch molding, and match the contour and line of the body.

 

Ah, these must be aftermarket then. I will post some pictures when i buy the car. Thank you for the information. -Bob
