How hard is it to put the smooth style not sure what they are called ground effects from a 91-92 firebird on an 88. not the trans am style but the other.. Do i need to change both bumpers or are they just covers ect? Also how much can a set be picked up for thanks again...

 

I have an 88 bird and I also have the 91 gfx for my formy, form the looks of it the sides are pretty much the same, you need the welded rocker panels. the front and bacl look to be pretyt much a bolt on. le tme know how your search for the gfx goes
