Banjo vs. Tube axle

[Jerry Collins <jerry.d.collins@cox.net>]

I have a question. I am in the process of rebuilding a 1965 MGB which 
has a banjo differential. I also have a tube axle. I am wondering which 
is better to use in the rebuild. Another thing is th banjo axle has wire 
wheels and the tube axle has steel wheels. Can I just interchange the 
wire wheel spindle on the tube axle and use the wire wheels or do I need 
to have the specific spindle for the tube axle? Thanks in advance for 
the advise.
