Ifen you decide to replace the starter , I went with a Delco unit from pep boys and got the lifetime warrany one to. It was like $60 and only replaced it once and it was free. The starter that I have in there now has spun the motor a million times , been submerged , sat outside uncovered for 2 years (rain and shine) outlasted two batteries and to this day does not flinch when I push the start button . Maybe thats just me .
The dude might have meant the "shorter bolt" . If there is no tension on the bolt , it is totally retreivable .
There is a bell housing that has a place for a starter up high on the back . It is a reverse rotation starter. and between the bell housing and starter your probably lookin at at least $500 . If your lucky and you might be . Rexmar.com has a great online catalog . You can also call them , very helpfull bunch .
