87! 4.2 Start up problems

My 87' 4.2L YJ wrangler chewed up the teeth of 2 new starters in a week and on the one that was on there first the whole nose cone had broken off. When i turn the key is get a loud grinding almost to the point of making my ears ring.

I don't know what the problem is my uncle said its probobly something with the flex plate and someone else said the flywheel was the problem but it doesn't look that too bad and another said the starter wasn't shimed right but I don't think it would happen a twice if that were the case.

Can anyone else help try and pin this one for me, because right now I'm looking at $800 for a clutch job and I really don't want to pay that.

Could be several issues, after to replaced the starter when you started it did you hear a high pitched whine when you let off the key? If so your started would need shimmed. Did the teeth grind when you first turned the key? If so then the teeth were not engaging properly. Are you sure you are getting the right number of teeth on the starter gear? There should be 9 teeth on the gear if you have a 4.2.
