I have a 71 Z28, manual trans. I bought a 96 Chevy Tahoe mini-starter. From reading threads here and the directions it said it should not need shims. I put it on and it needed something! I shimmed it with a 0.060 shim and it is still grinding It has nicked the teeth of the new starter and a few on my flywheel ring. I will add a larger shim but was wondering how to check the alignment without hacking my flywheel or the starter. without pulling the bell housing. I can remove the trans inspection cover easy enough. But how do I get the starter to push out the gear without hitting it with 12 volts (while mounted).
