A 76-and up 5 speed trans is a left side shift trans, and while the gear clusters are the interchangeable with the earlier right shift 5 speed stuff , the whole shifting mechanism is and inner cover is different.
If you are putting it in a pre 1976 (right side shift) Unit Triumph case then all you need to do is get a 1973-1974 5 speed inner trans cover and shift mechanism, and I believe any 1968 and up right side kicker cover should work.
The bad news is the 73-74 inner trans cover is very desirable and hard to find.
The real question might be why did you want a 5 speed?
it is not an overdrive geared trans. the final gear ratio of a 5 speed is the same as it is on a 4 speed, it's just got shorter ratio gears in between.

Sorry about calling it a 650, it is really just habit.. I was informed that, there is a couple of easy mods that would make it work, so that is why I considered it.. I was told by a couple of reputable builders and part suppliers, that I really on need to enlarge a couple of bearing mounts on the inner covers, because the 5-speeds have a larger bearing diameter. And that as long as I have everything from the 5-speed, I would be able to make it all work with my motor and inner case..
If it looks like it will get to involved, and the gear ratio doesnt really change, then I may just put the 5-speed on the market. The 5-speed really doesnt change the final drive? That does surprise me, because I dont see why people would do the retro-fit, and why the 5-speed bring the money they bring and are so quick to sell..
Thanks
