I did not have to do a rebuild, motor ran good, just replaced all the seals and inspected everything,pull the oil pan, looked up in the motor and checked timing gears. Chevs of the 40s has a good catalog and also good break down pages that look to have come from the Master Parts Catalog and they have plenty of parts. They have always beet super fast at shipping anything I have ordered.
I put a CD in with the bushing I sent you. It is a copy of the parts break down that covers 37's, it will come in handy for you.
