I've been told by numerous folks that rebuild trannies for a living to
keep the gears matched, laygear and main. I don't question the logic of
that.

I can't comment to that except to say either that you are right or that
you've been lucky.

Right. I agree. However, I need to point out that to get the correct
gears, you really need to do some "fiddling about". Case in point - in my
'74 TR6, I had a 2nd gear top-hat bushing failure and "collateral damage".
The 2nd mainshaft gear was toast (as was the mainshaft and 1st-2nd synchro
hub. At any rate, according to the "book" my tranny should have had steel
bushings etc. (BTW this was by the tranny SN, not the comm. number). Well,
because my car is an early '74 (CF14111), I had apparently gotten a
gearbox left over from the warehouse. It had all parts from the next most
previous generation gearbox. After staring at the parts and the TRF book
for quite some time, I gave up and called an expert (John Esposito) and we
rectified the mystery by having me mail him the parts in question for
identity. BTW - I'm the original owner of CF14111 - the 'box was in the
car from new.
So, to someone that is not so confident in thier ability, it's okay to
call in the experts from time-to-time. My general point was that I've been
very happy with my interactions of Mr. Esposito..
