Please don't weld a flexplate to a flywheel. That would be a possible disaster with the weld causing cracking and a flywheel explosion. Even if this is not a high rpm deal there is still a chance of welds breaking and causing problems.
Didn't think about that. I was hesitant to suggest welding on it, but not for a good reason. But that there is a decent reason.
What about some ears that would extend out and use the clutch cover bolt holes? Not sure if there is enough room in the bolt hole for a bolt from both sides, but maybe some extra long bolts from the back acting like studs on the clutch side of the flywheel and nuts to bolt the clutch cover on.
I would ask about adding some small screws to hold the tone ring on, but that would require some machining and I am trying to avoid that.
