I have been searching for a Kenwood SO-1 temperature compensated
crystal oscillator for the last 4 years. When I did find them (eBay),
they went for a fortune because I must not be the only looking for one.
I believe the SO-1 runs at 20Mhz...are there other units that could be
substituted? I believe the Kenwood SO-2, with also runs at 20Mhz, is
still available. Can the SO-2 be wired in place of the SO-1? Or is
there more to it than that?

Perhaps check out http://www.icmfg.com/tcxofaqs.html and see if they
make a TXCO which is suitable, or can be adapted to work with the
supply voltages and output-signal requirements of whatever piece of
(Kenwood?) equipment you plan to use this with? They say that their
TXCOs are available at frequencies of up to 20 MHz, as standard items,
and that higher frequencies may be available.

There are probably other manufacturers of TXCOs that you could adapt.
