thank you for all the great advise. dont have access to asphalt. But when we were unloading it off the trailer. (no wheel) we dragged it off the trailer and to would not budge at all. Im guessing this is what side lined the truck 40 years ago. It doesnt look like anyone has been inside the hub since it was parked.
1. Is there a good service manual for 58 GMC 370?
2. Where is a good place to buy parts?( mostly see stuff for 1/2 or 3/4 ton truck)
