Question Differences in driveshafts

I have a 1955 panel which has the original 223,6cyl. with the Fordomatic trans and stock rearend. I need to find a drive train for it, preferably stock. How much of a difference in shafts is there between a manual trans. and one for my application? I've heard mine should be about 56 1/2 inches long and that appears to be about right by measurement. Does anyone know where I might find one or am I looking at having one made? Any advice is appreciated.

My experience with more modern cars has been that the manual and automatic trans driveshafts are identical. Can't say if that's the case here, tho.

You might also want to pay special attention to the spline count. I seem to remember that some manual transmissions used an output shaft with fewer splines than automatics but I can't say for sure if that applies in your situation. It's something to check though if you should happen to find a shaft the right length.

It's a 28 spline shaft, there is a difference in Length between an Auto & Manual trans Propeller Shaft & unless you are able to locate one in a Wrecking Yard, it's best to have one made custom.
You also have to find a Specific Auto Trans Mount for it, which is also mounted in a different spot than the Manual trans's.
