95 trans am question
As far as any way to add them to your existing fender... a really good custom fiberglass guy could probably do it or modify a 98+ fender to fit, but you would have to talk to them to make sure.
I know the lower section of the fender is the same, right above the vents, as the lt1 fender. The top of the fener is curved different. I wanted to add vents to my lt1 fenders at one time, but just decided to change the entire front end.

After giving it a little more thought... you could get donor LS1 style fenders with the vents, chop them right above the vents... and then chop your fenders in the same place and then fiberglass them back together. But you would want an experienced vette fiberglass type guy to tackle it for you.
