Jeff,
That's the same part as is used on the TR4 and TR4A. The spacer fits
between the bottom of the steady bracket (nice term for it) and the top of
the gearbox extension. The only purpose I can see is to take up the space
between the steady bracket and the gearbox. I have that greasy bit
somewhere in the garage, which I can find and measure, but I think you would
be just fine using washer(s) of appropriate thickness.
Have no idea about the jam nut. There's plenty of space there on the TR4,
relatively speaking.

List,
I'm finally able to put my transmission back in the car (1975 TR-6)
after several months of resealing and too hot to drive it anyway. There
are two 1/2" bolts that fasten the transmission end housing to the
mounting bracket. The RH bolt, which is 1/4" longer than the LH, also
holds the "steady bracket" for the gearshift extension, and has a spacer
on it. This bolt also calls for a jam nut instead of a regular bolt.
When I took all this apart, I don't recall seeing a spacer, and it's not
in my bolt bag. This had been out at least once or twice before, so it
may have got lost. I can't find any dimensions for the spacer.
So, two questions:
1. How thick should it be? It's easy for me to make one, if I know
what size.
2. How important is it, anyway? There must be some clearance issues,
since the jam nut is in there too, but I don't want to wait until it's
back in the car to find out I need to fiddle and fettle to make it fit
right.
TIA,
