38 coupe, the spicer transmission is a 5531 without any suffix letter. 2.0 to 1 in 1st, 1 to1 in 2nd and .72 to 1 in 3rd. here are a couple of photos of the mount. I still have to paint it and the transmission.
My rear driveline is assembled to the correct length, I need to weld and paint it. The front driveline will need to be cut again since I changed to the T98 4-speed. It is about 2" longer than the T9 that came in the truck.
