pinblock inserts-- or not

[Michael Spalding]

David,

I like your idea - but you need to figure out how to join the old and new
pinblock while attached to the plate, otherwise there will probably be
enough flex that you will end up re-fitting the flange anyway.  Good luck,
and let us know how it turns out.
