As far as my 1943 GMC CCKW goes I have found all my bearings and seals are available at Napa and at bearing houses. I know we share some bearings with the Chevrolets. I love these rigs and found mine sitting in a wheat field in Oregon. Bought it for $650 and towing it home was insane! It wieghed about 9000lbs and took every bit of my '96 dodge diesel to pull it home. Check out my CCKW build on my signature. Mine was used after the war to haul a small cat, it was sure used up.
