Yup, we've used both types and probably have a few of each around.  The special gearboxes I've built mostly used the actual diff cover and shifter original to the car.

The type that adapt to the cover in place of the remote shift housing seem to be from 70s pickups and small engine estates and vans.... the 850 finally expired around 1980, but until then, most had the 22G1128 'left-overs' (remember, rod-change came along around 1973 with cases like the small-bearing 22g1832 and DAM3220).  The remote shift housing and parts were much more complex and expensive, so a "cheapie" magic wand was supplied for the basic small bore models that grafted onto the standard diff cover.

It's not uncommon to find Disk brakes and cv axles... I have installed the Cooper S 7.5 inch brakes and late CV axles to go with the hot rod 1345 and the 4 synchro magic wand!

This short video shows the empty 4-synchro box with the shifter/diff cover original to my 67 Moke bolted up, and I show exactly what happens in all the gear positions:

Alex - That is an interesting comment. I will get a picture and post it later. It looks like the standard magic wand  installation rather than any kind of adaptor. Another curiosity, is that the car was fitted with 7.5" discs at the front which also makes me wonder which version of CV joints it has. One of the original owners did a lot of good work on this car - adjustable rear suspension "trumpets", lizard skin coating on all engine bay and trunk panels, billet rockers, +20 pistons and of course the engine and transmission swap. I am on a voyage of discovery to find out what else might have been done.

Depends which type of magic wand you have fitted - one requires the diff housing to be changed, the other is just an adapter plate under the standard 1128 diff housing.

Metric is for people who can't do fractions...

It's a pretty easy modification to adapt the magic wand shift assembly onto the 22G1128 4-synchro gearbox. I built one for a Mini Moke using the original shifter, and have done several for pickups or other 'sleepers' to keep them looking stock. The Hardy axles are nice and strong, so that's a big improvement over the the old rubber u-joint coupler. It may be that the car came originally with the unusual auto transmission, which did use the hardy spicer style axles.

As for final drive, if its apart, count the teeth! If it's all assembled, I show you how to determine your final drive in this short video from my youtube channel:

My latest question is to help me identify my transmission and final drive ratio.
The engine is from an MG1100 with a 12G206 head. The transmission however has a magic wand shifter but the transmission is marked 22G1128. It also has Hardy Spicer drive joints.
From my research so far, it would seem that the magic wand shifter AND transmission might be from the original Austin 850 engine that the car came with from the factory with the later hardy spicer joints being added later.
Its a mystery. Anyone have any ideas?
