383 440 swap. Same flywheel?

I'm thinking a "register mounted bearing" may solve the hole problem.
But not the whole problem. I'll need to get this thing apart to find out more about the flywheel balance issue. And imput shaft length.

More to follow after the front end and brakes are sorted out.
PST is going to get an order soon.
