I have a '72 K-20 that I will be removing the th350/205 combo & driveshafts from soon to install an '80 th400/205 combo. The trans was rebuilt about 10-12k ago. That was about 8 years ago but I don't drive it much. Only thing it really needs is some transfer case seals. Works great, I just want the 400 setup in there since I have it. I also have an auto column & linkage from a 2wd truck.
