A company called "Haneline" or something like that has the door locks and window kits. Another co I read about can sew up a set of custom seat covers done in your choice of pony upholstery, colors and all. The great thing about 'stangs, you can literally do about anything. Rack and pinion steering? Yep. Independent rear suspension? Uh huh. The only thing holding you back is your own imagination and, if you're like me, your wallet
