1950's pinion bearings
Get out the binoculars, you got some hunting to do. Fun trucks, get some pics up in the Early Deuce Forum when you can. If you have purchased "New" parts from a cross reference to replace old parts, can you post the new part numbers. Building a database for these trucks, to cover all 'new' replacement part numbers, will be much easier with more info, merci.
The pics are from the old Levy Auto Parts Company that folded in 1987. 707652 710143 for the pinion bearings.
Hopefully you can read the numbers and they work for a cross reference. Otherwise you'll pull the bearings and drop them on the desk of a supply company who may work hard to find you some.
Brain Asbury is publicly listed in the MVPA Supply Line magazine but check your Private Messages PM ...and I'll get you a number. He's in Ontario and has helped me greatly.
I'm thinking you'll find what you need real easy once you start networking locally. Lots of "OLD" boys are hiding parts and if they see someone younger with a hope of actually completing a truck.....they may give up some of the gold.
Welcome aboard!
