Thanks for the tip! I found a few at around a buck apiece. Now to do due
diligence to see if they will fit my parts.

There are a few adapters over on that "auction" site.
Do a search on 14 pin smd to 14 pin dip.

Your comments on layout made me think again of how to implement these projects.
How do you use a 14 pin SMD IC? I could try to connect it with flying leads
but I'd like something better. Is there some kind of socket for these devices?
Or a generic board to receive such things?

I actually tested various 74120 dual 4-input NAND drivers which produce the
sync output on my B&K function generator to find ones which would provide the
fastest and cleanest pulse. AS (advanced
schottky) and FAST (fast advanced schottky TTL) were the best for me.
Modern inexpensive discrete logic however can do a much better these days.
One interesting thing I learned is that the dual 4-input NAND pinout overlaps
the quad 2-input NAND pinout so in a properly designed layout where only 2
gates are used, either part can be used.
