identifying transmission gears

[krwilson5]

I just picked up a T86 overdrive transmission for my 57 wagon. It is apparently out of a 61 ford car and appears to be just what I need. The trans and overdrive unit are in great shape, all except the imput shaft which looks like it was exposed to the weather. The shaft that goes into the pilot bearing is badly deteriorated. I can't think of a way to fix this so it looks like I need another imput shaft. My question is, is there a parts book available that I can check out how many different imput shafts were used in the T86 and their application? is there a good source of manual trans parts. thanks
