Parking Brake Cable - Advice Needed

[Chaparralman1974]

Good morning everyone and Happy New Year!

I am in the middle of installing a 4" lift on my '67 K20. The rear axle is an Eaton HO52 but I am using 11" drum brakes off of a later model 14 bolt rear end. Since the 11" drums are a bit smaller than the original 12" drums that were on the Eaton the rearmost parking brake cables that run from the backing to the plate are too short. It is now even worse (super tight) after installing the lift blocks. I am looking at Inline tube to see if I can get a custom set of cables made up. I am also going to pick up a set of new cables from a 14 bolt to see if they are a bit longer. However, if I do get new cables made up, how much longer do they need to be? I am thinking about 6" or so, but I have no idea how much slack should be in the cable.

Here are a few pictures of what I am dealing with.


Thanks, Clay
