I transplanted the 308 posi into my El Camino and discovered the problem.
Here is what the rear end spring perch looks like on the original.I need to remove these perches and have them welded correctly to the new rear end.
The other joker welded them too far forward rather than centered over the axle tube.
I still need to figure out what it came out of so I know what to order for brake parts.
The drums are different as the set off the 74 has a thinner area at outer edge of drum.
The rear shoes were the same...as I used the best parts from each rear end to complete the posi setup.
The 308 unit had all new adjusters and hardware,but the shoes were falling apart.
The drums off the 74 were like new,nice and thick,the others from the donor are rough.
