Let me try to help with all that, thanks Bob!
(Bob's answers in BOLD below)...
Dang, nobody is taking a shot at much of my original questions yet.
Trying again:
1a. The factory drums are the finned type in the rear (11" x 2.5") and non-finned
front (11" x 3") with a spring around them, correct?
My '68 with June 5th build date and the 11" x 2 - 1/2 rear shoes does not have the finned drums on the rear.
All 4 drums has the springs.
1b.Further, we can't use c-body 11x2.5 rear drums because of the extra "hooding"
on them, yes?
1c. Are the currently available "Bendix" new finned rear drums worth a spit?
1d. Where would one find the springs for the front drums new?
When I was doing the restoration on mine (2015 - 2019) I saw the springs for sale, but I cannot recall where. It could have been Ebay. That will take some research.
2. What year was asbestos eliminated from brake linings (and if known, what were
the part numbers for "the good stuff")? I recall even "back in the day" the
manufacturers tried going with sintered metallic linings in an effort to replicate the
stopping ability of the former asbestos linings...with dubious results.
Must I use the linings available from musclecarbrakes.com to get shoes that
have actual "bite" like the factory linings did?
3. If I find new, but very aged components (such as wheel cylinders, master
cylinder, etc.), do they deteriorate on the shelf to a point where they are no
longer trustworthy?
I would not use 50 + year old wheel cylinders/ master cylinders shelf units without replacing the seals. My personal opinion is that the rubber would break down once the brake fluid hits them. Just my 2 cents.
4a. Is the master cylinder for all drums the one with a 1" bore? Is there any
difference amongst those available with that bore (identifiable by various
different lids, example)?
4b. Is the Bendix-branded reproduction master cylinder currently available from many outlets
Chinese? Is it worth a spit? Anyone actually using one of them?
