Ok, thank you. I did quite a bit of reading on the meltdown and hopefully eventually will be able to also do some re-wiring too. I did clean up all the connections on my recently acquired metal frame one and my truck end connections, although they looked pretty clean. I read up on Mopartruckparts Tech section and followed their advice, getting one of the last years of the metal frame (1975?)used off of feebay, and I swapped that in yesterday (again, not the one pictured, I think that's an earlier one and mine isn't corroded). I think the earlier metal ones had the big loop in the frame on the left side, like the above one? Those condensors were never mentioned so I was curious. Everything seems to be working well and fits well. The metal frame is supposed to prevent the melting of the frame, along with keeping clean connections of course.
Facts are stubborn things.
