Hey everyone I am looking to swap ground effects from an 91-92 style to an 86. I know I have to drill holes for the rear quarters, rockers and door pieces and maybe the front spoiler (don't have that piece yet so I am not sure) but a long time ago before I got the parts I read on here somewhere about patterns on where to drill. Now I can't find anything like it on the search! Any help on info or references would be greatly appreciated. Thanks in advance...
