T14 bearing bores and journals

Was wondering if anyone knows the bore and journal sizes and tolerances on a T14 mainshaft and input shaft? I haven't been able to find them online or in any of my books.
Reason I'm asking is I'm about to finish assembling my transmission and and the input shaft seems like it has a lot of play.
It may just be because it's not being supported by the main bearing, but I would like to make sure everything is good before I assemble it all into the case.
Thanks
