What is the wheel base of your panel? The drive or propeller shaft for the sm420 is shorter than the standard 3 speed, that has an extension housing. The longer shaft is the same one found on the HD 3 speed, 4 speed, and hydramatic trucks. If you have the 32 truck the longer shaft is split with a center bearing, the 3 speed short shaft is not 2 piece.

Kicking self for selling off my Taskforce trucks.
Still looking for an LCF or conventional big bolt in decent shape.
