John,

I suggest that you send the holders, with the old crystals, to International
Crystal or to any competent crystal house.  Simply instruct ICM to change
the TX and RX from the existing frequencies to the desired new frequencies.
It'll cost you about $100 for the pair, but you'll wind up with crystals
that are guaranteed to work on the new channels.
