I was nearly ecstatic, because I figured to be educated on original park brake systems. But then I reached the rear cables. Looks like I have some things to pull before I approach that. I need a rolling truck before she's set on jack stands for restoration. Still have never done a brake job

This is a full tear down, and it's getting close.
Anyway, I know enough to say I need new front, intermediate and rear E-brake cables. This build is original intended, but I have my limitations (e.g., exhaust, radiator, quasi-original A/C). In your opinion, should I waste my time chasing NOS cables, or can you recommend real good replacements?
Thanks for any input.
