I can't help you directly, but here's some data for you regarding the R10.
I just (Feb08) rebuilt a T-96 with R10 OD for my daily commuter, 63 Rambler American. (I've got the "Twin Stick" version, with the two-year-only wide ratio 2 - 3 meant for "splitting" with the stick-shift OD ... five forward speeds with two levers... kool) Lots of the AMC T-96's had R10s on them. The T-96 is not only weak, it's getting really $$$ to buy parts for.
I also have a plain-jane AMC T-14 in the pile, a decent all-synchro 3-speed. And it sure looked a lot like the T-96... so I did the comparison whilwe the T-96 is apart.
You could pull the R10 unit off a T-96 and BOLT IT ONTO the T-14 with two exceptions:
* You need to bore out the back of the T-14 case, that currently has the output shaft bearing in it, to accept the R10 adapter. Fairly straightforward machining job, just needs accurate placement and size.
* Here's the bummer: the T-14 output shaft. Rather than extending out through the tail housing to meet the yoke, it instead is short and fits into the planetary jobbie in the R10. You'd have to fabricate this part, though in AMC-land there WAS a T-14+R10 OD available, though it was rare, so the part does exist, and I have it's parts number. I've never asked the likes of Northwest Transmissions if they can find one (just what I need, another !@!@!$$ project.)
* There's also the matter of the Reverse-OD lockout pushrod, but you really could just leave that out.
I hope this helps.
