The axle was swapped for a 2.56 "road axle" several times back and forth at my Uncle's Pontiac Dealership when i went on trips to New York in the car.

I am glad that it was reunited with the car it came from.

What is the timeline on the rearend? Starts out with a 3.23 then gets the 3.90 from engineering...Bill Sherman grenades it and has it replaced in 1964 with what the 4.33's? Then Tom you buy that rearend in the 70's and ??????
