Need T5 main shaft specs!

I'm rebuilding my T5, but the only part that needs attention other than the parts included in the rebuild kit (bearings, blockers, etc) is the main shaft. The journal that the roller bearings between the input and main ride on is pretty beat up. I talked to the guy at tbtrans.com and he said he had no used parts and a new one was gonna be close to $400, no way. So I asked if he ever heard of anyone turning it down and pressing on a new race and he said yeah all the time, great news!
Now I just need to know what the OD of that journal is supposed to be so I can give that info to the machinist if I find one in the Shelbyville/Indianapolis area to do it.

Also, I was hot on the idea of putting in the cone bearing in place of the flat roller and thrust bearings and bringing it up to z rating, but then I found out my input shaft is a 19 tooth and the cobra shaft needed to do the conversion is 23 so that killed that plan...

Don't know if this will help but it is good info:

Also there are some photos here

that show a repaired input shaft with one shot of the vernier readout that might be what you need.

Thanks for the links blue86!
Looks like .831" is what they used, and although that's not exact data from a new shaft it's a lot closer than I was before!
Yeah chris's rebuild guide is what i'm using, great stuff!
