If anyone is using information I've posted about constructing an aux trans. setup. I found a good part number for the throwout bearing and carrier I used. Mine came off a Cockshutt farm tractor, but it is the same one used in the 1947-48 Dodge Powerwagon. The entire assembly - the carrier with the bearing is a NAPA N1313 for around $70. Just the thrust bearing itself is: N1087 (at NAPA) or 2062(BCA) or CT52A-1 (Nissan-Ford).
I also found it for sale at a vintage Dodge Powerwagon parts place for $35.
Bearing only CC581499 $25
Sleeve CC581500 $10

For putting sealed bearings in the Ford Model A trans:
New sealed output bearing is box # SKF 6306-RSJ or on the bearing - MRC 306SZ The old unsealed output bearing was New Departure Endee 3306
New sealed input bearing - # on box: CR 6208-RSJ actual number on new bearing: SKF 6208-RS1 (or R51). Old unsealed bearing was: New Departure Endee 3208
Thanks John. I put this information on the Aux transmission page.
