any pin is ok in SS and the .990 pin is the most common in use but there seem not to be any legal aftermarket rod ava. with that pin bore,but you can ofcourse bush the oem rod,not sure how they feel about bushing down an aftermarket rod that has the specs shown already? have you seen the other thread that should be interesting for you?
