Crack in Starter clutch plate

[user 79399]

Help please. New member in need of advice. 1988 VMX12U, 31,800 miles. Crack in starter clutch plate from roller spring retainer hole to outside of plate all the way through the plate at 1 o'clock position in picture. I saw the stock replacement starter clutch kit available on Morely Muscle site. What comes with the kit? Where should I source the gaskets and whatever else I might need to put it back together. Gaskets for covers, copper secondary gear cover lower bolt seal, any o-rings needed? I also need one of the stator retainer Philips head screws, one of mine was missing when I removed the stator cover.
