[DeTomaso] u joints

Wed Oct 6 12:48:34 EDT 2010

One other thing I'm considering is to move the trunion closer to the engine.
The stock location puts it too close to the body.  With some careful
grinding here and there, it should be possible to make the shaft straighter
while also avoiding possible contact with the body.

BTW, the hole in my firewall for the shaft is currently removed.  I'm going
to place the shaft where I think it belongs and then I'm going to move the
hole appropriately.  I've enlarged the engine access hole by about 3" to
make it easier to work on the engine.  If you've tried to install a fuel
pump, you know how big of a pain it is. The hole is almost large enough.

I'll take pics once I have it done.

Dear Boyd, Justin and Tony,

When Dennis Quella was showing me the functional, pretty and improved shift
linkage U joints recently, he specifically mentioned that they *did* require
drilling a small hole or dimple for the allen bolt to sink into and have a
positive grip. In my recent experience with disassembly and re-assembly of
the rear most shift linkage, I do think that the PPC/Flaming River U joints
would work much better than the aged and neglected stock U joints. I also
think that one would have to have the splined shafts and U joints
disassembled in order to perform the countersink/drilling procedure. FWIW.

Warmest regards, Chuck Engles
