I am thinking of building my 66 coronet into a road racer and entering it into the vintage class.The problem is I dont know where to find road racing parts for vintage mopars.I had a magazine quite a while ago and it had an article about an autocross edition of a coronet.I cant seem to find the issue.Can anyone help me find a company that specializes in mopar road racing parts for vintage mopars?
Thanks all.
