Let's try this again in plain text:
So here's the issue - I'm running TR-6 U joints. But the housing on
one of them is so beefy that the pinch bolt won't actually pinch it
tight on the steering shaft. When I rebuilt it last time, I even
relieved some additional metal out of the "slot" with a cutoff wheel
to help this. I can slide the shaft in and out of the u-joint
slightly. If I tighten the bolt any more I'll break it. This makes
me very nervous.
It appears that there is a Borgeson u-joint that's 9/16" - 36 spline
on both ends but rather than a pinch bolt it uses a large set
screw. If I drill dimples into the pieces it will firmly hold them
in place. I've got one coming.
The odd thing is that of the TR-6 u-joints I have two distinct
styles. One doesn't have as beefy a pinch area so the pinch bolt can
actually pinch the darn thing together and make it nice and
tight. Ideally I would find another one of those, but the current
manufacturing doesn't seem to follow that pattern.
I agree that the rag joints aren't a great idea - but that's not the
problem I have.
Someone mentioned using an MBG u-joint (heresy!) - it appears that
there are more than one which will fit an MGB - anyone know which one
is 9*16" x 36 spline?
Thanks, Tony

Here's another vote for the TR6 joints...all metal and a direct bolt
in. The units with the "rag joint" are only outdone on the the
"crummy scale" by the units with eight conical "faucet washers"
holding it all together. I do a lot of tech for the local clubs and
can't even count all of the bad, torn or extremely loose joints I've
found. Some were so bad the cars weren't allowed on the track until
the joints were fixed.
All cars that come thru the shop with any of the rag/taper washer
setups automatically get the solid joints installed...now that's
really a "safety upgrade" ...unlike the song and dances I've heard
for brakes, engines, trannies...oh wait that's a different rant!
Still tryin to keep it vintage...

Subject: [Fot] Steering shaft u-joint TR-4
My steering shaft has two u-joints in it. The lower one is a big
beefy cast thing that I bought from Moss to replace the big beefy
cast thing that was there before. The upper one isn't quite as heavy
duty looking but does a much better job of actually clamping onto the
shaft. I've tightened the sh** out of the lower big beefy one and
it's still not as tightly clamped as I'd like.
So... Where can I buy alternate u-joints for the TR-4 steering shaft?
Look forward to the advice.

PS - article on front suspension swap to TR-6 stuff is still coming.
