There's still a lot of R12 out there. Ebay has a lot of listings, they may or may not sell it without a refrigerant license, seems to run around $25-30 a can.
Or, (by law) recover the R12 that's in it and dispose of it. Then dump what oil you can out of the compressor, vacuum it down, install the 134 charge fittings, add some 134 oil and charge it with R134. That will be a permanent fix. The system must be in reasonably good shape for it to have "some" charge left. Be sure not to over charge it, R134 is very sensitive to charge, ease it in until the return line gets cool, and stop.
A ball valve with barb fittings will be a good heater shut off. Better than what the auto supply sells.

After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
