Air Dam

Can anyone post the correct part catalog name for the air dam for our cars? A Checy party # would be a bonus too.
Thanks!
(89 IROC-Z)

Thanks for the replies, after 14 years of occasional scraping, it finally cracked. Probably just got more brittle from age.

I have an 87 GTA my deflector is aluminum and is at a 45 degree angle. Is this factory? I can't see any illustrations in my serv. manual. Does anyone else have this?

I doubt highly that it is factory. Bad choice of materials whoever did it. Aluminum is not known for its elasticity!

I put my car up and was able to take a closer look-it's not factory
just looks well made.
But is the angle supposed to be 45 degrees or is ir supposed to be like an air dam straight up and down?

Severe cooling probelms! The car heats up at sustained highway speeds and really heats up going up hill.
I just ordered that part number but it will take a week to get out here so I will let everyone know how it works.
By the way this is for a 1992 and later the parts guy at the dealership said that anything pre 92 on these cars is pretty much discontinued.

Was it angled forward or back?
