I thought 71-72 was the change over years for tapered bearings, and there was a service bulletin for 70s and before to use tapered bearings as a replacement? I could be wrong there.
I think it's possible too that a casting date of April made its way on to a 71 car, since 71s probably started shipping in Aug/Sept.

I deleted my post because I thought I was wrong and seeing things in his axle shaft pic.
I did an archive search for 9799100 and saw a 1969 8.2 that DID have tapered bearings on the shaft.
Weird. Maybe OPH can straighten me out.
Sorry for the thread hijack.......
