Were there any starter shims with starter? Have you checked the flywheel? The grinding sounds like the starter drive gear and flywheel teeth arent messing.
Have you done a voltage drop test on the starter wiring? The starter has to be cranking for that test, just test voltage at both ends of wiring. The reading should be the same or very close.
Are you using quality starters? Oem is the best, may cost a little more.
