Get a new pressure plate, or use your old one.
Put in a new pilot bushing, that one is b0rked.
Also, check the flywheel distance from the block. Make sure that it's the same compared to the old engine (When the clutch was fine). Who knows, maybe it's been turned too thin, or isn't the proper distance because it's the wrong flywheel.
Get it done man! It's only couple hours worth of work, and you really don't need to pull the engine.
