I don't have any problem at all with the concept of stripping the parts you
need off one drive to make the other work. After all, you'd be conserving the
number of complete drives: start with one complete, and one missing some
bits; end with one complete, and one missing some bits.
However, I personally would not dispose of any of the bits, though (except
things which can be easily found, and will continue to be so, like standard
fasteners); once they are gone, they are gone forever.
UNC/UNF parts are easy to source on this side of the pond: I imagine they'd
be easy to find on eBay, or if there's something you can't locate, let me
know, and I can run over to the store and grab it and mail it off.

For your purposes, you could probably get by with an M782 or M7820 (earlier
versions of the M7821); I'm pretty sure they are pin-compatible (the earlier
ones have circuits that aren't quite as good as the one in the M7821).

These are pretty easy to find on eBait.
