I know that a late model 17 inch wheel will not clear the upper control arm on the front of a 68, but will an 18 inch wheel clear? i would really like to have these wheels http://cgi.ebay.com/ebaymotors/18-9...1QQihZ018QQcategoryZ43958QQrdZ1QQcmdZViewItem but i dont know about fitment. I'd say spacer are probably in order, but i thought that since maybe the wheel was18 it might clear the ball joint.
