It'll be a bit of a kluge, but you can substitute that

There's not much in them if I need to replicate one.

Back when I was a pup, we had an old 1960s Motorola TV in the shop that had a bad encapsulated module for the vertical circuit that was NLA. I told my dad I'd make one, so I just got a breadboard and put together the half dozen caps and resistors and painted it with Corona Dope (didn't need it, but it looked better). Worked great.
