Hmmmmm- - - -that's obviously a conversion I'd never heard of. At one time, before Patrick's went belly-up, they sold a shifter conversion that moved the handle forward to about the middle of the case of the 3 speed Saginaw trans without relocating the shifter bell cranks. If the shift linkage can be routed around the governor assembly successfully, it shouldn't be terribly difficult to fabricate something similar to operate the 4 speed shifter. It would require a couple of heim joints and a piece of thick flat stock to avoid flexing as the handle was moved through the shift pattern.
