You may be in luck. I ran into a similar problem with my Cockshutt 80. As we know, same tractor in different clothes. I realize that you live in Texas, but this might help. I live in Edmonton, AB.CA. My local Continental engine dealer is able to access pistons, rings and a whole bunch more parts for these old tractors. As it stands right now, he is getting the block prep work done after I found a crack in one of the cylinder bores. He has also found a local fella that pours babbit bearings. There is a place that has quite a few of these old tractors that might be able to help you out and they are just outside of Medicine Hat, AB.CA. I can't think of the name off the top of my head but I will get it and forward it to you. Hope this info helps.
