Here's what I did for a "holding brake". It's in-line with the rear brakes. Depress and hold the pedal, turn the valve and release the pedal. Works remarkably well. Pretty sure it's not "compliant" with mechanical "emergency brake" requirements but hey, I'll take care of me. Holds for days...
It's easiest while they're out so I say ball joints, clean/inspect and pack bearings, and definitely confirm that the ratios match. If it's and AMC 20 rear you already know that the pinion seal is leaking so do it while you can stand up instead of laying on your back!
How much does that slider/step bar thing weigh? Looks substantial. Progress is good for your sanity. The house if full here and we're all doing something "distantly". 8" of snow would make for a nice gym class setting, maybe on a 4 wheeler!
In the 2nd pic of post 192 is that a crossover (H) pipe just behind the T-case?
Looks great and sorry to hear about the temp working situation. We'll all be just fine when this is over, just have to keep a positive mental attitude.
I hope that when you bark the pipes on that thing it reminds...
Seems to be one of those things that is just hiding in plain sight...keep up the good work. I'm home schooling today and can empathize with anyone else doing the same. Shop class is probably going to run a little long today, prepping the Dana 44 disc brake knuckles for the Bronco!
