if it is the one I'm thinking of it was at a repair shop in Butte when I first saw it. 14-15 years ago, talked to the shop owner, he said he wasn't sure what the owner was going to do, the shop was having issues with the carb flooding the engine, IIRCC. left my #.
went thru town a year later, the shop moved across town, stopped in and talked with him again, he said it was sold to somebody who came in with cash and it was gone.
the owner wasn't a person but a large orginisation.
I did know who owned it originally, and IIRCC, it was registered as a 1968 according to the paperwork in the glove box.
are you the guy who has a wanted post on craigslist?
