I put a cruise control in my 56 Bird last year. Not really stealthy as the governor unit sits in the inner fender panel. Its an Audiovox CCS-100 and it works pretty good, but not as good as the factory installed units in my everyday cars. I has a bit of trouble getting it going at first, but it worked good on my trip to Oregon and back (from NJ). I got it off ebay.

Anyone ever put an aftermarket cruise control on a Tbird.  Toying with the idea but would want to do in as stealth a mode as possible.  Any recomendations on manufacturers. 

PS.  if you think I'm nuts, I've been told that before
