All,
 
I now have a 56A 5 speed for my B10 rally car.
 
The obvious difference between that box and the 56 4 speed in the car is the clutch mechanism.
 
Can someone suggest a tidy way of making it work please. 
Edit in: I didn't get any clutch mechanism with the gearbox.

I am pretty sure the 56A would fit without having to modify the tunnel.

If you need to modify the tunnel to make it fit you should shorten the the clutch fork, this will help with clearance issues and save you having to modify the tunnel.

People have either:

A) Cut the tunnel and put a box in provide clearance for the clutch fork (why the hell do they call it a fork?)

B) Panel beat the tunnel to provide clearance.

Modify the fork, you won't have to massgae the tunnel or cut it. I haven't done this yet but I plan to do so the next time I have the box out (and re-weld the tunnel back to original).

Mike is on the money, use a 1200 cable and perch.

Wouldn't it increase the travel?

A small dent wouldn't have cut it for mine, I had to cut a hole in the trans tunnel which was a bummer. And since looking at the clutch lever I've decided to do that next. It's worth a try isn't it?

Ok sorry the fulcrum on the other side of the carrier isn't it. Whoops sorry I was thinking of it as it being at the middle.

I'm all muddled up.

Either way, another member on 1200.com insisted that the 56A 5spd box was a bolt-in without mods to tunnel.

I'll have the modified fork soon, reducing it by that small amount won't have much influence on pedal pressure, if it does maybe it's best to up the gym workout on your left leg. But I think we can admit that a harder clutch pedal is still fairly weak in these little cars.

Can anyone suggest a wrecker in Melbourne who would have the bits I need for the conversion?

Help please, I am desperate to get this job finished.  I need a 1200 thrust bearing and carrier to suit the 1200 arm.
 
Is anybody in Melbourne (or nearby) able to help?

I don't think he can, I think he has the stock gb.
 
The thrust bearing can be bought from a parts store, or have a look on ebay. As for the carrier and arm I think you might have them confused for two separate items. They are the same thing (unlike the factory 1000 part which is two parts). The carrier which holds the thrust bearing also serves as the arm to which the clutch cable connects to.
 
So generally you'd also need a clutch cable and perch from a 1200 or 120y(confirm?).
 
Is there a wrecker near you? A 4 speed 56a can be had for anywhere between 25 and 75 dollars so you are probably better to buy a whole gearbox and get what you need off it. Just be sure it has the parts you need. Keep an eye out for these parts on ebay as well.

I wish I had just bought a 4 speed for the "accessories", it would have worked out easier.  Anyway I have the required thrust bearing and carrier (thanks to Randy at Nissco) and the 'box is bolted up and in the car ok.  The thrust bearing has a larger diameter than the 1000 variety so it is pushing the fingers on the pressure plate closer to the pivot point making the clutch heavier.  I have a 1200 cable all the way to the 1000 pedal and it seems to be working put is not the permanent arrangement.  The fork is periously close to the body but once I get the rear mount lowered to the correct 56A five speed height I should have working clearance.
 
I had the motor out for another job so have not fired it up yet, probably tomorrow.
