Sources for out-of-date differential carrier bearings?
I am in the process of rebuilding a differential and have run into a snag. I need a source for a timken bearing with the number 29177 and a race with the number 29334. I have tried Egge Machine Co and the local auto part stores. The auto parts stores that i have checked can't get this bearing and race as they are not being manufactured any longer. Does anyone have these parts or a source where i can get them?

Re: Sources for out-of-date differential carrier bearings?
I have checked several of the suggested sources and have come up empty handed for the original carrier bearings.
As a next step to my carrier bearing dilemma, I began investigating the possibility of modern bearings and altering the differential unit to fit. What I finally settled on is a bearing made by National with the part number 30209-A. As it turns out, this bearing is a much better, heavier design, with the same outside race diameter and inside bearing diameter. The difference being, the bearing width is about 0.06" wider than the original ones. The easy fix for this was to machine 0.03-0.06" off the face of the bearing adjustment rings where they mate with the cone race. This allowed me to adjust the carrier assemby for correct ring/pinion alignment.
The differential axle felt seals have been updated with the modern National 471424 seals. The axle adjustment rings had to be bored out a couple of thousanths to accept these seals. The pinion seal was replaced too with the National 473448 seal. To make this seal work, the pinion housing was bored a few thousanths larger and about 0.125" deeper. A hub ring was made and pressed onto the (odd size and worn) pinion flange hub.
