Right ok. I get it

So I'm measuring the old shoe against new. First thing is that the e brake
laver on the new shoes is 1 mm thinner. Assuming a properly adjusted
ebrake lever would keep the adjuster bar in alignment, I doubt the larger
gap between bar and shoe/ebrake lever is an issue. Depth of slot the big
fork fits into is the same however. 11.5 mm by my measure.

Measuring old shoe against new, ironically, lining plus steel bracket
thickness end up being identical.
Regardless, it's proving tough to get consistent measurement from mid point
of shoe lining OD to
a straight line from each contact patch at each end of the shoe.
So far though it seems im seeing a 1 mm difference but. could be full of
doo doo on that measurement.

I traced an outline of each end of each shoe bracket where they fit into
lower pin and wheel cylinder piston. The bottom portion is nearly identical
so I transferred a measurement of contact patch shown on old shoe, to new
shoe. It's roughly mid point. My lower pins are somewhat worn
though. The upper end is nearly the same shape.

I know this seems like overkill, and my methods are highly suspect, but
if I'm correct about these particular new parts fitting so close from the
get go, it's possible some other shade tree could install the parts only to
end up with glazed shoes and drums.

YMMV though.

Neil.
