I have a G16B block with Vit G16 manual bellhousing, the RingR bolts between the Vit bellhousing and the Toyota gearbox.
I used a Vit G16 flywheel and pressure plate with a Toyota Surf turbo diesel clutch plate with 4mm turned off the outer edge.
Throwout bearing is Vitara. The kit is made for US spec cars which apparently run a nylon sleeved throwout bearing which they ream out about 1.5mm with a dremel. I decided to run a standard unmodified throwout bearing on a turned down throwout snub instead. That way if it ever needs a clutch kit the only bit I'll need modified is the clutch plate.
Spigot bearing is different too but it is an off the shelf bearing that's cheap. Can't remember the part #.
The only drama I had with the whole fitup was the throwout snub on the W56 wasn't long enough* and the throwout bearing was sliding off the end and getting jammed.
A new longer throwout snub was turned up and all is good.
Pics in my build thread or search RingR on Pirate.
* The addition of the adapter plate which from memory is 25mm thick, between the gearbox and bellhousing, pushed throwout 25mm further forward on the snub. Hence a longer one was made.
