I wasn't concerned about the "D", I was looking for old studs that had been machined off.

he said that is paint from when they painted the drums on the axles and it went through he holes in the drums lol

and it also looks to be the same size pattern just smaller holes

on the inner hub can you get an exact measurement...im not finding any hubs with the inner at 2.25...closest i see is 2.283

Sorry, my eyes aren't what they used to be. I went back and checked. The measurement on the drum itself is 2 5/16 with the axle just a hair smaller. 9/32 would be .28125 so your 2.283 sounds right.

The best I can tell there is a big M in the upper left, 3HE just below the middle on the left and TM below that. On the bottom right is a big E. The drum fits the hub fine. The shop replaced the shoes because they hit the ground when the drum flew off. I don't know if they are the same as what was on there before, but they're 1.75".

I think 10x1.75" is also a B-body size.

Here is a picture of a front drum on a '68 GTX... looks identical.

I think you are on the right track because the rear drums are 1 3/4". I looked at that earlier and the references I found show that B-body drum is a 2.83" hub diameter. I have a feeling the brake drum he has is some that Moser bought and punched as needed for their application.

Trudyduster said earlier that Moser could make what ever brake drums he needed so I would contact them and see if they can do what the op needs.

The 8 3/4 we was working on yesterday was a Moser set up and they used a Ford drum.

With the smaller center bore I am starting to think you are right. It appears the 5x4 bolt pattern drums have a 2.31" hub register:

And the 5x4.5" drums have a 2.81" register and come a little wider:

1968 Ford Mustang V8 is 2.43", otherwise looks very close. CENTRIC Part # 12261002
 
So let's assume that these are re-drilled SBP drums.

If you find a 5x4-1/2" bolt circle drum that fits otherwise, but the center register is too big I would consider making a hub ring, this would be a one time deal and then you can buy off the shelf drums.

Just a thought.
 
you could send off the old hub to moser and have them make you new hubs...im not understanding what your meaning by a hub ring. i would deff call moser and ask what it would cost and seeing how it looks to be their axles see if they knew what part number they could give you to find a shelf part

I looked at the 68 Mustang too and I thought the deep offset they have is too deep for his application.

I made some for a 15" Chevy II Centerline on my 5 on 4 axle. The hub ring was mandatory for me to drill the 5 on 4 pattern. I ID'd the Chevy register and OD'd the Mopar register and ended up making a brass ring that was a perfect fit on both. I punched the ID of the centerline at 3 points making little gouges and the ring sticks in there pretty good now. For a Ghetto bolt pattern redrill on an old drill press, it came out pretty good, no runnout! Can still see my measurements....

My problem is that whatever I end up buying, I have to convince the shop owner's insurance company to pay for it. I'll talk to Moser on Monday, but I'm sure the insurance company won't be happy to hear "custom made part."

custom means more money but why did the wheel fall off...their mistake?
Click to expand...

Yeah, their fault. Owner said maybe the wheel wasn't set correctly before torquing the lugs. He didn't do it so maybe the tech just forgot to torque them down. Either way, their insurance is covering it. The adjuster only allowed for $28 for a drum, so I'm going to have to get them to provide a supplement for the difference.

The raised center part on the axle locates the drum. If the OD of the axle center register is 2.28" and the ID of a drum that fits is 2.8" then you would make a ring with an ID of 2.28" and an OD of 2.8" that the drum would locate to. This is common practice to make high performance wheels align to a hub so that they are "hub centric" and not "lug centric" (located by the center of the hub, not the lug nuts).

If they really want to argue the point the rear end housing could have been damaged from the fall to the pavement and rear end will have to be replaced drum to drum
