My Summers Bros Spitfire axle broke, too (vintage 2002-2003). My car
very nearly went on its head as well. Mine broke at the taper from axle
to the hub.

I received the following response from Mark, containing a request that I
repost to the list.
I'm somewhat familiar with the Summers Brothers Axle set-up for the
Spitfire/GT6. Photos I have saved on my hard drive seem to include a
U-Joint assembly that is different than the stock Triumph unit and
utilizing Spicer parts. I don't have part numbers or knowledge of the
history of what has been offered or used by others. I've discussed this
topic with several on this list in years past, and I am pretty sure
there is at least one FOTer who has done some development work on the
hubs (Chuck Gee?), and I think that one of our members actually sells
these Summers Brothers units (Joe Siam?).
I certainly don't want to open up a can of worms, and appreciate the
fact that these attempt to supply a need for a very small market.
However, I would be really happy to have Mark's U-Joint issue cleared up
for us so that we know what needs to be done to make these things work
I bought axles from Sommers Bros in CA. Told them what I had and they
sent me new ones I installed then and thought I was safe. WRONG.
Basically they used stock Spitfire u joint castings with new u joints.
They did not tell me or ask me if I wanted to use Corvair parts, how the
heck am I supposed to know about that need? They have been doing this
for 30 years and they are supposed to be the experts and such right??
Anyway the u joint casting is sort of fine but the u joints themselves
are weak and that is what failed.
So now I got great axles that are splined to poor strength castings and
no way to modify or reuse them to use them again. 2000.00 down the tubes
thanks to Sommers Bros. Not to mention the potential life damage and or
the damage done to the car overall.
I don't know how to reply to these and have them appear on the site so
if you do please do for the sake of others so they don't have this issue
like I did.
