Hehehe, well I am.  I guess I may have started the confusion.   I was
incorrect when I included the Salisbury axle in my request.

Here's what I think might be [close] to right????

Tube axles:
3.9   MGB for sure, actually 3.909:1 as Barney points out
3.2?  MGB automatic as per Larry, I'm not sure about this
3.07 MGC (still available new) as per Lawrie
3.6   MGC as per Lawrie

Banjo axles:
3.9     for sure
4.3    for sure MGA
4.10   MGA 1600 MkII as per Barney
4.55   as per Barney, he has a part #, must be right, has Barney ever been
wrong?
4.875 as per Barney, see the 4.55 comment
5.xxx from MG TD/TF models, more than one ratio as per Barney

Seems to me I read the T series gears may need to be machined to fit the
MGA/MGB banjo carrier???

What did the 4.55 and the 4.875 come in?  Special tuning?
