Hi cr34dad,
I have a C4 mated to a Dana 20 T shift TC that I'm no longer going to use on my Bronco project. The C4 was reportedly re-built when I got it and the TC has been re-built, neither have seen any miles since then.
The only down side is that I'm in the San Jose, CA area so shipping may be an issue.
Let me know if you're interested in discussing further.
