I made some of this spacers to Sweden hotrodders last year.
This is 32 spindles to Lincoln backingplates ( I think 42/48 ) no udea of whsg drum,

I had the 39/40 spindles and Lincoln 41 backingplate/drum ( like that flat look )
I seen Spencer in 1950’s used the 39 deep backingplates.
On pictures text say 41 Lincoln but thats not correct.

In my earlier post I stated I had to make up spacers, from memory, .170" thick. Different application; I'm using 35 spindles and drums....The way I see it, you're using 42-48 spindles AND drums....this means they are matched and in the correct orientation to each other; it is the backing plate that needs to move outward 1/4"-3/8" as you've already surmised. Make some spacers up that both spigot onto the spindle flange, and have a spigot to correctly centralise the backing plates, at the 1/4-3/8 thickness and you'll be sweet! Good luck.

Old thread with helpful discussion from Richard (EV8G).

"Some of the original Lincoln-Bendix brakes did not have the outer ring, but did
have 3 mysterious "buttons" around the outer backside. Maybe 39-40? The
rings ARE available to be added for those who want them. The new drums have a deep
outer groove that the edge of the brake plate fits into, which helps keep dust/water out.
Otherwise, the new plates are thick stampings, but lack some of the finer detail of the
originals; as with most stuff, the originals are the way to go IF they can be found in decent
(not rusted to hell) condition and $ is no object... since they are usually not cheap!

There are also different versions of original Lincoln-Bendix brake plates and corresponding
hubs/drums, whereas the reproductions, which are often advertised as 39-40 are
ACTUALLY the scarce, one-year-only 1941 (fronts) that are the same offset as ALL rears
39-48 (shallowest design) and which CAN be used with Ford hubs/drums. The original 41's
used Lincoln front hubs (all front hubs are the same 39-48) and the, again one year only,
flattest drums, which results in the narrowest front track BUT cannot use Ford or KH wire
wheels on the flat drums, or the 42-48 "medium" front drums, without a serious spacer on
the flat drums or a half-serious spacer on the medium drums.

The "trickest" Lincoln-Bendix fronts are the actual 39-40, which have the deepest offset
and have the smaller bolt pattern that fits 32-34 and 35/36 spindles. A special
kingpin/bearing kit must be used on these, and must use the Lincoln hubs BUT the new USA drums fit, which solves the problem that most Lincoln front drums that can be found are machined beyond the limit. The new drums are good for 12.090" so they are also thicker than the originals to start with. These provide the narrow front track, but allow the option of using Ford or KH wire wheels, using only the standard Wire Wheel Support Ring to
support the inside of the bolt circle.
