The starter wheel is not actually that far off. The hole in the chassis doesn't really look big enough for use with a starter box. And after doing a small amount of research, I'm not confident I can find a compatible lower profile mount.
So here's what I'm thinking. I think I'm going to go for a stock hyper flywheel and file out the opening slightly.
I'll be fine removing the flywheel I think. But replacing the clutch looks harder. Any tips without using a clutch removal tool?
