1970wrktrk, not trying to hijack the thread, but flatbeds are kinda in the same family.
Baradium, there's an outfit near me called
J&I Mfg that sells flatbeds that I have seen literally all over the country. They've got a wide variety, and have figured out most of the accessories/addons, too. I priced one a while back for the '69, but backed out. It was $800-$900 depending on options. Here's a pic from their website (sorry, it's mounted on a f**d).
Grendel, that figures. Just a little off my beat, or I'd be calling you.
