Question:
It reference the 90865 as a drum with 9/16 studs then in upper right it talks about the brakes as 12 x 3.5. I don't think 1/8 smaller shoe depth would make that much difference. Mine does have the 4 bolts, I just need the distance between holes, mine are about 3.5". Give or take a little as I didn't have the wheel and drum off.

Helpful Expert Reply:
Electric brakes such as Electric Trailer Brake Kit # AKEBRK-8 do not fit specific axles. These are 8,000 lb rated brakes with a 4-bolt mounting flange pattern and are 12-1/4" diameter x 3-3/8" wide, so you would need that mounting bolt pattern and a hub and drum assembly that allows these brakes to fit.
I've added a link to a video review of the brakes for you to take a look at.
