GM part # 12621399 Flexplate with spacer and bolts.

There's a guy on here that makes the output shaft I think, can't remember who it is, maybe someone can help.

Very glad to see you stickin it out Josh, you won't regret it.

GMpartsdirect lists that as just "flywheel." Are you positive it comes with the spacer and bolts too?
