DW, you already know more about this than I do. My truck came with a heavy duty clutch and flywheel so that won't be a problem for me. Have you found a 261? They are getting harder to find. Probably a few farm trucks nearby, you're in a good neighborhood to look.
I still get back a couple of times a year. My parents live there. Rock Springs and Green River are really booming, at least they were last year. Evanston is staying steady. We had our big boom in the late 70s - early 80s. As far as the Pinedale/Jackson area, I've heard the wealthy out -of-staters are buying up all the decent land making the prices unreasonable. Too bad, it's one of the latest pristine areas to get ruined.
