Did you check driveline angle longitudinally? My 63 Classic was
wacked hard once (probably 20 yrs ago) and I had four wheel
alignment checked; it's parallelagrammed about 1" end to end.
Aligner said "its better than most new cars!", it tracks perfectly
and tire wear is perfect.

But I found the driveline out of alignment. It was easy to check,
reasonably easy to fix.

I ran a string taut from the harmonic balancer to the center of
the rear axle, and put little wedges such that the string wasn't
resting on anything. I found that the rear of the
transmission/front of driveshaft wasout of line with the other two
points; I re-drilled the crossmember to push the rear trans mount
over into line.

Since you installed the new rear, it might be worth checking.

Also, driveline angles are pretty tight, tolerances within a
degree might be required, and you may have to determine what's
proper since you have a non-stock rear. I wouldn't copy the
torquetube angles, since it's such a wacky system, but instead
copy a same-size later open-driveline car. Pinion angles are
important.
