QuickTime T-56 Starter Issues

I'm wrapping up a T56 magnum swap using the QuickTime bellhousing for an LA. Went to fire it up today after many months of work and 'crunch '. The starter is grinding the flywheel bad, it sounds like it's in a bind

Has anyone had starter clearance issues with this bell/combo? Ive read mixed messages about whether you can really even properly shim a mopar starter. There aren't many options when you search for shims. Brewers carries this but no thickness is listed and it's labeled as a seal. Any opinions or similar experience is appreciated. Thanks
