I found a whole ground effects kit for $50 with a new front clip and sideskirts, but the original rear bumper. The guy wrecked the car and now doesnt need them. Will these bolt up to my 84 GT? It doesnt have ground effects but I would like to put some on there will these fit? I have already switched my front end over to a 90 LX front end so I know the Gt will fit I am highly skilled in making stuff fit on there so that isnt a problem. I just want to know how hard it will be to bolt up. Thanks for everything
