T140 Belt Drive.

[Monaro]

I am going to fit a belt drive kit to my 73 Triumph. I want to run it dry and have everything in place except I need to find out either the brand , part number for a sealed bearing to run in the clutch hub. Failing that can someone supply the OD of the gearbox main shaft. Thanks for any help. Cheers, P.S. I already have the kit which does not have the bearing.

That said, you're asking for a very specific measurement and that may be hard to come by.
