It is possible your car doesnt need the shims. If they are being installed with the starter try installing without them and see if that helps. They could be holding the starter out just far enough it cant make full contact with the flywheel.

Starters are usually held on by two bolts. The shims go between the starter and the engine and secured when the two bolts are tightened. The shims provide for the correct positioning of the starter so that the starter pinion gear engages with the flywheel correctly. If no one checked for the need for shims, it is possible that the starter gear would slam into the flywheel without actually mating with the flywheel gear teeth. That would explain the knocking. If in subsequent tries the starter gear does engage with the flywheel, the grinding noise is because the gears meshed too tightly. It probably does need shims.

A one eight clearance off the shaft allows the teeth to mesh properly! if not it just hits without going into the flywheel teeth! No noise is correct! Too lose or tight sounds about the same! If a miss fire while cranking it can bust the starter housing! It is normal to check the teeth when replacing starter!
