MGB A-Arms and MGA A-arms - length

[Andy Ramm <aramm@concentric.net>]

Does anyone know the specific A-arm length of the MGA vs. the MGB?  Are
the items the same?  Are they mechanically interchangeable?  What about
the length of the front shock levers for these two?  Same or different?

Are there any cars from the T-Series with A-arms that are mechanically
interchangeable with B A-arms?  Were those arms longer or shorter?

A gold star to anyone who can accurately answer these questions!

Thanks,

Andy
