Reply to "Seeking advice prior to rebuilding the brakes for 1332"

In my personal opinion and experience, "figure out exactly how the e-brake works and fix" may be optimistic.  Be careful to not over-tighten its range of motion, as you may boil your brake fluid on one or both rear wheels (easily diagnosed and addressed, but discovering that on an interstate highway in traffic is unnerving, don't ask me how I know).  Apparently these days there are better solutions, generally requiring some money.  Some have adapted a Tesla e-brake though some of that seems to have become relegated to salvage yard parts and which sources are maybe drying up, or (probably better) contact Scott at saccrestorations.com.  My current car has been converted to probably a Hall line-lock e-brake (that's basically just a forklift brake), a system never designed to truly hold on any incline for any length of time given the weight of a Pantera.  I realize there are some Panteras whose stock e-brake systems magically seem to work as intended, but I suspect they are in the minority.  Short of finding one of those true solutions, I personally recommend a couple of basic wheel chocks for when it really matters, for now (Harbor Freight has a collapsible set that's cheap).  And park it in a gear, of course.  Everything else you wrote sounds good to me.  You can find threads relating to both the Tesla and Scott's e-brake system here.  Another consideration could be, if you choose a more modern solution, you could probably cut out the stock e-brake bracket and crossmember on and between the frame rails and install a removable crossmember to allow you to later drop the oil pan if you ever wanted to.  I should also mention that Porterfield brake pads (I want to say RS-4 off the top of my head) can noticeably improve stock brake performance).  I think you would want to request ones with welded "tabs" to lock into the slots in the calipers.
