installing starter

ok i finally got the old starter out and the new one in. it works if not bolted up and goes clunk hitting flywheel and not spinning bolted up. been shimming it more and more. tried bolting it up twisted and it ground on flywheel. never had such a time installing a starter. saw previous thread something about wrong flywheel but wouldn't the starter be matched? truck ran fine before starter went so replacement should bolt up...shouldn't it? any suggestions?

the only post i've seen (i did a search) that sounds like mine said he was told the flywheel didn't match. i did a search of both autozone and a used parts site and both only list one flywheel for a 93. the reason i posted is because i've already shimmed (lets see 4- 1/32 and 2-1/16) 1/4 inch seems excessive

I'd loosen it way off, then try tightening it a little at a time... then switch to the other bolt thghten it up a little, and so on (mine wanted to go in twisted when I didn't do this)

in case someone else finds themself in the same situation figured i'd tell that i replaced the battery cables at my wife's urging and that solved it

thanx man ,most on here suck you dry for answers and never tell what fixed the problem,so the next bastard never finds the fix so....Hooray you are an ok person tnx old man tnx to the old lady too !
