RE: Summers Bros Axles
A list member, Russ Moore has a Spitfire axle design that uses Summer Bros
Axles (I don't know if these are the same axles Mark has) and Corvair U
joint flanges.
Here's a list of the PNs from the Bill of Materials he sent me. I've had a
set on my spitfire race car for a few years now with out any problems.
Prior to that I had a set of Steve Johnson designed axles that were
stronger that the stock ones, but used the stock spit U joints. I would
break / wear out a joint at least once a season. One time it put me into
the wall at Limerock.
Russ has a shop, besides being a Spit racer, and can give you more details
if you like.

Outer roller bearing J-2012 Torrington $ 13.32 -4
