My approach would probably be to machine a 'top hat' that would go over the OD of that and mate with the flat surface of the plate and either weld to or have screw to hold it to the plate. Probably could find a plastic cap or similiar that would do the same and not require machining. Find something that fits reasonably snuggly and slobber a bunch of hardening type RTV in there when you put it on and if you're lucky that will seal it and hold the cap on.
Unwise to weld directly to the 'button' as that is a pocket on the inside that support the shift fork shaft.
Gasket on the plate/body surface can either be made from gasket material or just use RTV.
That is actually a great idea thanks. I hadn't considered just finding a cap and RTVing it over the old one. Any idea how hot that should get? Aside from the exhaust being there. I am just thinking I could 3d print a cap but I am wondering how hot the exhaust will get in that area. I figured if I took off the plate I would end up with a new RTV gasket already. I was debating any modern JBweld type material as well. Not sure if thats what you meant by the hardening type of RTV?
