I am not sure there are many 40 year old harness out there that are in good condition. Most are cracked and brittle but serviceable. Jeff Bowlsby is your source for a good one. I have one that as the saying goes "was working when removed" but would not classify it as good. I would say it would be a last option.
I have one of Jeff's harnesses. It's nice to be able to move wires around without hearing a .... cracking, crumbling sound.
