Brake drum question
I have a question about how my front brake drums should be mounted to the hub. The drum has two sets of mounting holes as seen in the picture below:
I believe this is the correct way to mount them. Is it? Also, why are there two sets of holes? Is the other set used on other truck models or axles? One set of holes has a raised shoulder-like thingy. Now, why can't the manuals use straightforward language like that? Everybody knows a doohickey and thingamabob when they see one.
Just another confusing mystery that isn't cleared up by my huge library of shop manuals, parts books, fix-it books and the hundreds of pictures I took when I disassembled everything. I didn't think to take a picture of how the drum mounts thinking it could only go on one way like the rim.
Thanks!

If the bolt pattern is the same and one set of holes has the 'shoulder', I would guess that the correct set of holes would have something to do with a difference in rims being used. Just a guess, I'm sure someone will have the correct answer based on fact.

Nobody can answer this question, either? I thought folks on FTE knew everything there is to know about these old trucks. Granted, these are obscure questions but surely somebody knows why Ford did these things back in the day. And what about the spring nuts that hold the brake drum on the studs? How many per wheel and does the concave side face in or out? Don't let me down, you know-it-alls!

IF you are going to put the spring nuts back on the concave side faces the drum.
The spring nust were origanly put un when the truck was on the assembly line so that the drums wouldn't fall off.
I always threw them away, they can be a real PITA
