Gordon,

The last time I did one of these blocks I put some bits of more-tite putty
on the pin block section, in the approximate location of the holes, and set
the block into position.  After removing the block, the holes positions will
be accurately located by the impressions left in the putty. (more-tite is
that gray semi-sticky putty for sealing air leaks in windows).
