A couple of great suggestions!!
The starter was 'new'...but it hasn't been proven.
It is possible the spring is weak.
As for bolts, they are not OEM/application specific...I think I just got some grade8 bolts from Ace. But if the shoulder of the bolt (or lack of one) is helping with alignment, that could very well be my problem!
I'll see if I can track down some bellhousing starter bolts.
