Brian,
If you promise to use a new circlip, I'll send you a new (good used) third
gear for postage.
The folks who told you to replace the layshaft are probably into those sissy
all synchro boxes which eat them up. TR3's rarely require them. You ought to
take a hard look at the teeth of the laygear, though. They tend to be a wear
item on the TR3.
I have never figured out why folks want to fit a later box to a 3, or a
diaphragm clutch either. Might as well fit an automatic. And if you go that
far, why not a V8? But then they might just as well have bought a Corvette
in the first place.
And yes, the multiple screw drivers and 2 hours of grunting worked for me
back in the 60's though, since then, I've purchased the proper tools from
TRF.
Good luck.
Regards,
Ed Woods
