Final update: I was able to get the Teraflex e-brake working pretty darn well with those new Dorman brackets. The brake finally holds the Jeep on a front facing downward slope now. Part of the issue is the difficulty in getting the shoes and brackets on without any bending or offsets. Once you have some small bend or angle in the brackets, it won't fix itself. You need to take it all off and do it again. It took a lot of swearing.
Once that was done, I would tighten the spider wheel up so that I could just barely turn the wheel with my hands and body weight. I'd then drive it for a week, then tighten the spider wheel again so that I could just barely turn the wheel. Drive it for a week. And for a third time, tighten up the spider wheel, drive it for a week. With each week, you could feel the e-brake holding better and better. I was afraid that if I tightened the spider wheel super tight all at once in the beginning, that I'd glaze the shoes. So I did it over 3 weeks.
Anyway, that's what I did. Wife doesn't complain anymore.
