I sent mail to one of the authors on GEnie, and received the following
reply. I've been short on free time recently, and haven't tried it yet.

Karl,
Best answer I can give you now is the following:
Replace the resonator with a crystal from JAN Crystals (813) 936-2397
1.5578 Mhz, HC33U case, parallel resonant, 20 pF load cap., .005%
approx. $10 and 2-3 weeks lead time. this will also require circuit changes
as follows:
remove R2 1K resistor and replace with a short.
Change C2&C3 from 100pF to 33pF (DigiKey PN P4018).
You might try using left over 22pF's first.
I have the parts on order to double check the circuit but have not yet.
Sorry for the inconvenience and additional cost. JAN was the fastest
source with a reasonable time that I could find. They specialize
in small quantities.
 
Regards,
Dave
