Thrust specs

[CaverDave]

Can anyone tell me the length of a new stock thrust bearing (#3) journal?

I'm trying to fix a 2.9 that my friends grandfather supposedly rebuilt for him I could write for days listing the problems / stupidity I've encountered so far. I know the crank was turned .010 but not marked and the thrust is out of spec but I don't know if it's the bearing worn or if Grampa's machinist screwed up the thrust surfaces. I know I could just get a set of bearings and check but it's an 70 mile round trip to the FLAP so I would really appreciate any help.

Thanks, David

Thrust bearing journal length: 1.039-1.041

I have a pdf of many of the useful measurements for a 2.9 if you want it, pm me your email address and I'll send it to you.
