NY WTB: rear parking brake cable for 1972 Suburban 4x4 3/4 ton K20

Hi, I'm looking for a rear parking brake cable for 1972 Suburban 4x4 3/4 ton K20. Both of mine are missing!

Apparently, for this variant of the truck the cable bolts up differently to the backing plate, and I haven't found a vendor that sells a reproduction.

Inline Tube indicated that they could reproduce the cable If I sent them a sample, and then offer it to customers. So if I can find one, I'll ask them to do that.

Hopefully someone has a used one they are willing to part with.

Thanks and regards,
Nick
