1968 cougar bought a set of rims from 2005 mustang rears fit great ...however there's something rubbing... It's my friends car so I haven't seen it yet. I think from what I found online its the upper control arm but he said its bottom rubbing. Does anyone have a cost effective way in order for him to keep these rims...I've seen upper control arm relocation kit and expensive lower control arm kit...... Any help would be great
