I happened to notice on my 77 cutlass parts car it has a black plastic air deflector under the rad, my 75 Cutlass does not. Is it a few years specific 76-77 or have something to do if the car had ac??
Either way, if my car didn’t come with it, I doubt it would hurt to put it on my 75 with no ac . Thoughts?

That piece should also have a lower air dam to help direct air into the radiator so it would be helpful regardless of AC or not.

 

Thanks Fun
