Firstly, I would say the crack has occurred because of the localised stresses caused by the welding.
Secondly, I would say you should never weld anything to do with a flywheel even though it is steel (not cast iron). Mine run to 6000rpm+ btw.
Thirdly and last, the UNF will be a bastardised conversion from "proper" threads!! Clutches were Austin-factory built.
Well, you did ask....
