I didn’t like the universal set of parking brake cables with the kit, so I did some research and found a stock set that I can work with. I believe these were for an 85 K20, two RH cables.
I trimmed off approximately 1/4 of the spring to work with the travel of the caliper arms.
Cables ran!
I just need an intermediate cable and the brakes should be done. I’m measuring 102”, my two OEM options appear to be ~95 Dakota or Ram Van (102”) or ~85 Chrysler New Yorker (101.35”). Both are out of stock so I may just have one made.
