I have a Farmall 460 LP powered tractor, with a large amount of sentimental attachment. Unfortunately it's been sitting for a long time and the vaporizer gaskets are shot, i'm bleeding propane into my coolant lines. I have been in contact with every Case IH dealer I can find, and have only gotten as far as "all those parts are discontinued." I haven't been able to find much online, and I am starting to lose hope. I know on some other forums on here people have mentioned a guy down in Oklahoma, but didn't seem to know if he was still in business at the time, and those posts were already a couple years old. I don't know much about these (cars are more my area of expertise), I believe it is an Ensign vaporizer, and it sounds like they've been out of business since before I was born. Any help would be greatly appreciated, the tractor was my dad's before he passed away and i'd hate to lose it due to such a small discontinued part.
