Parking Brake Cables for Rear Drums (unequal length?)

[EscapeRacing]

I am finishing up that rear end build and swap in my 79 Trans Am that I had posted prior to the old threads being erased and all is generally going well, but ran into an issue last night so reaching out for some help.

I am installing new parking brake cables (just the ones that go from the drums to the front cable) and all the part numbers seem to indicate they are the same length for both sides. However, i cant seem to see how that works because the one from the passenger side has to travel much further to the equalizer than the one from the driver side.

If anyone can 1) confirm they are unequal lengths, 2) shoot me over any part numbers for the cables, or 3) happen to know the measurements, I would sure be appreciative.

If they are identical for both sides, then something has been modified on mine and I have to go back to the drawing board because I cannot get the passenger side to reach the equalizer...

Replaced mine last yr on '78 drums, I will look at the receipts tonight. Think I got em from Inline Tube. Will investigate & get back.

I just ordered WS6 ('79-'81 Rear Disc) brake cables from Second Gen Graveyard last week.  He supplied me cables (stainless version) from Inline Tube.

Thanks, this is really interesting. The disc brake rear ends pretty clearly show unequal length rear cables, but the drum brake rearends seem to call for equal length. I have drum brakes and just cannot make equal length work so will try using the disc brake rear passenger side longer cable.

Thanks again for helping me out - i miss all the historical posts but sure glad we have this back.

They operate differently, rear drum cables are both facing forward. Rear disc are one forward, one backwards with the calipers, like shocks.

Okay, I have to apologize for creating this thread. This was 100% user error on my part and I feel pretty dumb about it.

The parking brake was engaged when I tried to install the new rear parking brake cables. I disengaged the parking brake (in the car) and the two fit right together.

Think nothing of it, If you made those errors, guaranteed so did someone else  so this will help others save some time and be mindful when doing it themselves...like me!!!

Think I've done the same, at least climb under there and start backing off the slack adjuster before realising. And yet, last thing I probably did before sliding under the car was check chocks and tighten park brake more.

That looks good.  Where did you buy them?  What brand?

These are just from the local auto parts store - O'Reilly. They are BrakeBest Brake Cable Part Number BC92680 and they were $18 each.
