I've got a question, but first the facts: 1953 3100 with a replacement 235, torque tube and 3 speed transmission.
Based on advice from another post, I want to buy an input shaft to use as a pilot bushing installation tool. I found a candidate online for a good price, but it is not from the same transmission as the one in my truck. The input shaft in question is from a 60-69 Muncie M21. My question is: are the dimensions the same and will I be able to use it for installing the pilot bushing and later, the clutch? Any information/advice is greatly appreciated.

They have plastic alignment tools that would be much easier to use and cheaper than an input shaft (unless you can get a freebie).
They can't be used to install a pilot bushing, but an input shaft isn't really the best tool for that anyway.

I put my transmission back in with the everything slightly loose )very little play) Once transmission was in, I was able to spin the flywheel and tighten everything down correctly. I am sure that’s not right; however, it worked!

You'll have a bushing installer you can pass down to your great-grandkids. Send me a PM if you want me to make one for you. Make the next 3" of the shaft a slip fit in a clutch disc and you'll also have a clutch alignment tool.
