Thanks for all the input folks. Here's what I ended up doing. Bought a new a/c clutch at NAPA for $90. It included everything back to, and including, the coil housing. I replaced all of that and started it up. A/C clutch cycled, but no cool air. I took it to a friend who has the gauges and is certified to put charge the freon. For another $100, he added freon and it works great now. I kept it with the R-12. At first it was a little slow on the cooling after sitting for about 15 years +. But after a few cycles through, it started cooling down and now it works great. Thanks again for all the input.
