Default New starter grinding my flywheel. How?

Hey guys I'm in a bit of a bind here. My starter is grinding against the flywheel, replaced it with a new one and still kept grinding. One factor was that my dustplate was the incorrect one and was just mangled up so I cut it along the starter area so it could line up at at the correct angle.

My old dustplate:


Now thanks to some help I was able to cut the dustplate area that acts as a washer between the tranny and the starter and used two washers. The washers are the same thickness as the dustplate. This is my new starter installed:


Even with the space and correct angle, it's not lining up correctly is grinding the teeth off the flywheel, with or without washers.

Am I missing something as to why it keeps grinding? It's only supposed to bolt one way in and even if i give it a push on the gas pedal you can hear it grind.

I really would appreciate some help, this is my Daily Driver and it's been down this whole month.

WTF happened to the bolt holes...? There's no way they are going to center the starter.

Happened a while back when the TT dustplate thing happened. The hole they go into is untouched, only the outer hole is drilled.

I was swapping starters again and it tends to straighten out as you tighten the bolts in, but it does have some play to it :/

What can I do here? This is my daily driver, I need it fixed and I can't wait any longer.

The problem is that those bolt holes are fubar'd... They are letting the starter move too far away from the flywheel. Beyond replacing the bellhousing, the only thing you can try is to make some shims to shove and re-position the starter. The only good part of the project, is that the the sound the starter drive makes is the best indicator of how well it's aligned. You'll know if you get it right...

The dust plate isn’t there anymore right? That plate is also a shim so if the starter is a little closer because it’s not between the starter and trans then it can grind. Unfortunately I found out the hard way it doesn’t take much to get a starter a little off and ruin a flywheel so be careful. I would try and make a shim (washers) to go between the starter and bellhousing. If you have good threads back in the bolt holes it should line up good when tightened down but as others have stated before that could be the problem.

Do you have any of that dust plate left?

Edit: If you do then make the shim out of it. I meant to say that before.

I already used washers and it didn't help.

I removed what was left of the dustplate because it was hacked up and making things worse.
