Wish I could help, maybe you can you order it from the UK.

: Glen,
: Can you tell me if the early GT6I's
: transmission mainshaft is smaller in
: diameter than the later GT6's?
: I thought I could use the speedo gear
: from my 72 but it is not the same size.

: Any conversion is going to take some
: effort & $$. There is nothing
: inherently wrong with the Spit/GT-6
: box, it just wasn't designed to take
: power/torque, and the 6 cylinder puts
: it at the limit; it's marginally
: adequate if you work it hard. It is
: getting hard to find decent used hard
: parts but the stuff is still out there
: if you look for it.
: I have never had any decent results
: bushing the mainshaft spigot. I have
: successfully repaired that, if the tip
: of the shaft isn't worn too bad, ie
: dimensionally OK. It involves an inner
: race which is a slip fit on the
: mainshaft (requires loctite), and a
: caged needle bearing which requires
: that the 1st motion be machined out to
: proper size to fit. This works very
: well but the inner race OD is just a
: few thou larger than the ID of the 3-4
: sync hub, so the loctited race has to
: be removed when the box is stripped
: down.
: I may be able to find part ##s, I have
: done a few boxes like this but it has
: been awhile, I do mainly the big TR
: boxes.
: Also when you are sourcing parts, there
: is an early & late GT-6 box.

: Don't misunderstand me I want to keep
: the
: GT6 trans but have already run up
: against a new parts wall. First/second
: gear very hard to find. Mine is pretty
: chewed up. The connection between the
: main shaft and the input shaft both are
: a little scored. The old roller bearing
: is quite loose. Ok to use a bronze
: bushing like the did in earlier cars to
: reduce the steel to steel wear on parts
: now very hard to find?

: The TR6 box in a GT6 is a common
: conversion for the racers but slightly
: more difficult in a street car. The
: rear NHV mount requires some clever
: fabrication for a street car while the
: in the racer it is ignored.
: Additionally, the TR gearset SUCKS for
: the GT6 and thusly requires the $600
: close ratio gearset from Ken
: Gillanders.
:
: Do fit the box You need the engine
: backing plate from a TR and an extended
: pilot bushing to engage more of the
: input shaft. The clutch slave can be
: mounted using the 2.5 Saloon mount or
: fabbed at home.

: Guess I am a throwback and date myself
: but.....I have most of the Triumph
: tools for gbx repairs and
: inspect/rebuild very carefully every
: one I do. I treat each one like it is a
: race car transmission.....Haven't had
: problems...knock on wood. Everyone has
: opinions, just voicing mine.

: The few TR6 gearboxes I have seen are
: quite a bit larger than the 3-rain and
: single-rail boxes. I imagine a lot of
: tweaking and fabricating would be
: required to make a TR6 gearbox fit. I
: expect a new tunnel cover would be
: required and that it would encroach a
: lot into the cabin.

: Sorry for bit of confusion, my car is a
: Mark 3 GT6. Transmission has had a hard
: life. Suzuki in Bugeye looked great fun
: but any alternate trans would have to
: be adapted by someonelse. I can
: assemble but I can't design. Thought
: about a TR6 trans but you never hear of
: anyone doing it so there must be some
: problem.
