Hi Alvin...a shim can't be too expensive to try and the starter is pretty easy to get to from underneath (no headers or exhaust in the way) so hopefully I can try that soon. Maybe it is a depth problem and that's all there is to it!
My searching so-far hasn't yielded any special starter bellhousing bolts but I'll look s'more.
In any case, I appreciate the quick response so far and I'll report back after I try some of this out.
