A few pages later a smaller picture does show the pivot plate.  Interesting the larger pictures do not.

If it was not intended to be used he may not have enough room to install one , anyway with or without will not cause the problem he's having. Ford shop manuals or parts catalogs were never perfect . Only my opinion  :)

That is true.  Neither of my cars have the pivot plate, as well as many cars that I have done brake shoe replacement.  I have found them on other '50's and '60's Ford vehicles.

I have seen the shoes cut for this reason. My past impression was that they were out of round but I didn't think about it that much.

If you look at the wear pattern on a broken in set you will rarely see a full contact pattern.

The set of shoes that I have are sectioned in three parts and you can clearly see a metallic content to them on the edges.

I'm wondering if the sectioning is an attempt at "correcting" this issue?
The segments on the brake shoes like the ones used in the 65/66 Shelby's and sold aftermarket to the high performance crowd are supposed to provide better braking in competition. The Shelby ones and the aftermarket high performance versions were of a semi metallic materiel.   The spaces between the segments better get rid of brake wear material,water sand ,mud etc. so that optimal contact between the lining material and the drum surface can be maintained. This is compared to the same non segmented shoe. Probably better dissipation of heat compared to non segmented too. Today I think instead of the individual segments the pad material has a groove made into it.

Have you tried swapping drums side to side to see if That will help you with more information?

Overkill is just enough.

Some people would just decide to throw them away along with parking brake link spring retainer just because those items made the job a little too hard  ???

^^^^  Car was purchased in 2004 and was supposedly taken to the brake shop after the chassis work was finished.  I highly doubt anything was done other than maybe some minor adjustments and topping off the brake fluid.  Before my purchase, car spent many years on the east coast which led to lots of rust.  The wheel cylinder bleeder screw was nearly rusted away!  I'll probably wind up purchasing lots of new parts and have my repair shop replace almost everything.  Many of the fittings won't budge even using Blaster and a line wrench.  Probably best to go with all new parts.  Backing plates are pretty rusty so I may have to source some replacements.  Having an arthritic knee makes doing repairs that I usually did now very difficult.

I'll be doing that in the next couple of days to see what I'm dealing with.  Since my whole assembly seems to be off center I need to focus on the cause.  Thanks!

For me sometimes the whole brake assembly just needs a heavy hand slap from side to side for the shoes and touching parts find their true center. Just what has worked for me over the years. Nothing fancy but maybe worth a try.

Parents and others have often told me I was "heavy handed "  ::) over the years  :)

My dad taught me how to do drum brakes many years ago.  He would say that when the job was finished one should be able to swing the whole shoe assembly from side to side by gripping the bottom.  The whole assembly should move smoothly.  Mine doesn't!  The left shoe wants to move up and away from the pivot pin.  I'll be taking everything off when I install the pivot plate and will check the emergency brake mechanism, wheel cylinder,  backing plate, etc.  Hopefully something will surface.  Thanks, Jeff!

While you have everything off, though you might have already checked these, see if the pads the shoes ride on, on the backing plate, are smooth and not grooved or other wise damaged. Some times it can be the smallest and simple things

Is your cross bar on the shoe or the e-brake lever?

^^^  The spring loaded side is on the shoe while the other side is on the lever.  Same on right rear.
