I purchased a Powermaster starter for my 455. Even with the additional shim they provide with starter I still do not have any clearance between the drive and the flywheel. The drive is right up against the flywheel. I even got another shim from them and it doesn't help. The tech at Powermaster says the maximum is 2 shims you can use on the starter. The flywheel is a new OEM style. Anyone else have this problem?
