Also Turnips, just bear in mind that every cobra chassis and body is hand made. Regardless of who made them (even Shelby himself, I'll bet) they will all have little quirks and bits and peices that aren't quite right and need correcting. Or things that you don't like and want to do slightly differently. Or just stuff you want to adjust to suit your application.
IMO you should think of it like putting together a jigsaw puzzle that doesn't have all the bits cut out yet, and has bits missing - you are going to have to use resources, your skill and experience and make it work. It is NEVER straight forward. And thats half the fun
