The 3-main MGB flywheel has the same bolt pattern as the MGA, just uses 3
alignment pins rather than 2, and those are on the same basic circle.

Fits fine, no problem there.

The rear axle is about the only thing I have had no trouble with on my MGA
in over 300,000 miles, and I run the crap out of it. Doing repeated hot
starts and power shifts with the race tires should be pretty hard on it,
but so far I have only needed a new u-joint on occasion. I have spare
parts for everything on the car (almost), but I don't bother keeping any
spare parts for the rear axle other than gaskets and seals.
