You can likely replace those with equivalent-function stocked ECL
chips (in
the $5 price range). Since the chips you mention are single
devices (IIRC
single D and single JK FFs), there are various modern
replacements. The
replacements aren't pin-compatible, and usually come in SO
package, but it
should be trivial enough to wire them in.
