Speaking of ball & trunnuin setups, - I had no luck finding someone to make
& balance a driveshaft for a 56 Plymouth. What I needed was a shaft that
had a slip yoke on the front (we put a 4-speed in the 56) and the B&T at the
rear for the stock 56 rear end.
I finally figured out that the B&T diff yoke can be replaced with the
(common) 10-spline yoke from a later model 8 3/4" diff. The splines and
seal surface dimensions are the same, the only difference is in the length
of the splined area of the yoke. The 56 B&T yoke was slightly (about .150)
shorter, and all I had to do was add sufficient "shims" to go between the
end of the yoke and the front pinion bearing. A "stack" of 8 3/4" pinion
shims was all that was needed. This allowed me to go to my "driveshaft
archives" and select a unit that was a "drop in".
End of problem.
Regards,
DaveG.
