Thanks Bryan: You are so right. If I posted a photo of my arms it would make some people ill!
I have succeeded with some crazy ass car part challenges in my time, but am throwing in the towel on this one. I can feel the tabs on the C clip on the left cable, but the right cable disappears beneath the lower coolant tube. Can't feel a thing! And then, there's the question of putting them back in!
I mentioned reading that someone removed the engine and I think that's the only way (in order to remove the coolant pipes.)
But the partial good news is that I did finally get some movement going back and forth and am now able to pull the clevis ends out by hand (as opposed to my slide hammer deal) Whether it will eventually loosen up enough for the shoe springs to pull them out is still a question. I plan to cobble up a way to hold the clevis ends vertical and drip feed thin oil - for a long time!
If that doesn't work, then someday if I ever sell this car on BAT, I'll need to add one of those famous BAT disclaimers, as in: "The Seller notes that the handbrake is inoperable."
Cheers,
Ron
