Going back to this thread, not sure what the outcome was for Geraint, but I am using a lightened 12v flywheel on my 24v engine, with a 12v gearbox (and push-type clutch).

If I put on a 24v gearbox, what are my options regarding the clutch - assuming I will be keeping my flywheel, as it's the only one I have?

Does the 24v clutch fit onto the 12v flywheel, or does it have larger mounting bolt pcd?

With the 24v gearbox having pull-type clutch operation, if I fit a 24v clutch, does the 12v slave cylinder fit onto the 24v gearbox, using the mounting bracket for either box?

Or should I stick to push-type operation and put the 12v clutch operating arms, linkages and slave cylinder onto the 24v box, and use a 12v clutch plate too?

Will put an uprated clutch in there if I can find a suitable one, whether 12v or 24v fitting.

Cheers,
John
