I had the same problem. I broke an axle. I put in a MGB rear
differential unit and axles into my MGA housing, something I wanted to
do anyway for the different ratio. I donated my remaining good axle to
Jim Knight of British Racing Green. (www.brgparts.com). If that is your
problem give Jim a call, he is a good guy.
