Last year I did the 727 in my power wagon which I got on a great deal because the transmission had lost reverse. He pulled the transmission out and got a supposedly good working long shaft transmission and he thought he could just change the shaft housing from behind. LOL he gave up on it and gave me both transmissions in the truck for an astronomically low price and all I had to do was replace the reverse band. When he showed me the piece that's missing in this picture I knew exactly what it was LOL...
