I haven't pulled the rear apart yet , just preppin, and the dodge part book threw a number at me that I couldn't cross through timken, which I also prefer to use if possible , If you look on Ebay there are a lot of folks who have parts that they are not staking their retirement on. You can get good unused parts that are from when these cars were made, thats what it's about. Both bearings are in the rear end on the pinion, the front of which is one number different than the rear but uses the same race.
At this stage the truck is completely apart. The frame and rims and other parts are powder coated, the engine is about to be rebuilt, the cab is in another garage waiting for more time and money, but I definitely will show it as time goes along. By the way the powder coated frame is hanging on the wall of the shop.
