Moss gearbox query

![Default](/forum/images/icons/icon1.gif)
Hi guys,
Just wondering if anyone has had experience rebuilding 3 synchro Moss gearboxes out there, especially in regard to the synchroniser hubs.
The Factory Parts book (pp. 16-6) shows, on the 3rd/4th synchroniser, 3 ***** and plungers, 3 springs for the ***** & plunder, plus 3 "thrust members", whatever the hell they are!
Upon stripping down my 'box, I find it has TWO plungers and SIX ***** with springs, and ZERO thrust members.
Does anyone know if these synchronisers were modified on later boxes, as the one I have has an unknown history, ie no idea what car it originally came from.
This "project" involves ditching the BW auto in my Mk2, for a manual stick shift.
Any help would be massively appreciated.
Pete

Pete, This is one of those 'if I were going there, I'd start from somewhere else' replies.
My car has a Moss box, but I've no experience of working on the parts below the lid. I have worked only on the shift mechanism. I think almost everyone would say don't bother. The Moss box is strong and mechanically efficient, but fairly (or extremely) agricultural in action. Many parts are difficult to find. It's better to obtain a later Jaguar all synchro and better still a 5 speed conversion. I think there should be a good supply of Toyota W58 Supra boxes in Australia. It's about as nice a gear change as you'll find. Dellow in New Zealand and probably others can supply most of the parts you need.

Thanks Peter for your thoughts. Yes, I did consider the possibility of a 5 speed conversion but I inherited an overdrive Moss box with another non-overdrive for possible spares, so I thought I'd stick with what I found in the Parts Department (back shed).
Plus affordability. Too much $$$ wasted on cars in my lifetime, keeping in mind George Best's experiences, less the booze & fast women!
Besides, I'm sorta content with spending (wasting) my time rebuilding the Moss unit, hiding in the garage away from the wife!

The challenge of making a Moss work well is difficult to resist (and rarely achieved).

Not without some drama I might add. The first attempt resulted in ZERO gear selection at all.
I have not disturbed the O/D unit. One look at the manual had me running for cover! If there's no O/D once back in the car, well bad luck.
Many more late nights to get the reconditioned 4.2 engine & gearbox installed.
Thanks for all the amusing banter.
