Just checked those modules out - might work if the accuracy was 2ppm or less.
As far as the crystal application itself, the frequency was common to PLL circuits in Tram and CPI CBs, CPI accessories (an FC-70 is the counter in question) and I'm not sure what else.
I managed to snag two used rocks off eBay last night which will hopefully be operative but I'm still on the hunt for a new one.
