Make sure that ICM did not quote you for:

My suspicion is that this radio is sufficiently drifty to begin with that
using a high precision crystal is probably a waste of money. But I could
see someone recommending it, and it wouldn't hurt anything.

2. Entire L6 assembly

ICM likely has the documentation for that entire mod -- and may be
referencing that -- and may be more than you want.

I rather recommend this modification.

Xtals are used in upper/lower side band select which replaces L6
assembly. I a surprised to
learn that ICM is able to research the NC-300 that well. These guys must
be good!

They are good, and they have been around a long time. They were making
the kits for the NC-300 when it was a current production product, and
they still have all the original documentation for everything they ever did.
