Yes, of course.  This is the most difficult part of making such an adapter,
and it has to be just right or the resulting setup will have severe
problems.

Very good point, I neglected to mention that.  There are only two precision
holes, and they are the ones that must receive either dowels or dowel-bolts.
But, they are reasonably obvious, since the attachment bolts are 5/16"
(except for the two for the starter).

I agree entirely.
