Great news!
Got the engine and transmission married up, which psychologically is a great step, as well as seeing them in place!
Took measurements of the engine mounted to the transmission, and from there to the center of the shifter, and that relation to the cab - we have a perfect fit. The shifter will be right where I need it in the cab. We will have to create something smooth to use as a shifter, but otherwise, it is coming along nicely.
