Does anyone know what the center bore (hole) size is on a SBP front rim for a 72 Duster with disc brakes. Thanks!

Referring to the hub. I am looking to determine what size the center hole in the rim needs to be to fit over the hub on a 72 duster with disc brakes. Hope this clarifies. Thanks.
 
Sorry i runs lg pattern but can check i do have factory small pattern rim i will measure the whole for you hop that helps.

The hub diameter is the same for drum and disc brakes cars with the Mopar small bolt pattern set up. It is the same as all sbp mopar wheels no matter the year. What you must look our for wheel clearence on the calipers. 13" wheels will not work on disc brakes from what I have always been told.
 
The bore is about 2.3" on the small bolt pattern wheel. Couldn't get my calipers on square that's why I say about.

I have a rim that wouldn't fit and it was 2.3" so it must be larger. It has the Kelsey Hayes front disc brake set up so it is larger than drums. Unfortunately the car in in for paint and I cannot access it to measure the front hub.

Maybe it is 2.85"

Anyone know for sure?

Sounds like you are trying to put a modern front wheel drive 100mm wheel on the car.

Again, the diameter for the hub for drum brakes and the Kelsey Hayes disc brakes are the same. The 10 drums hubs even share the same bearings and grease seals as the KH disc brakes.

I have both of these cars that have both brake set ups and switch wheels back and forth.

I know the 2.85 is about right for the big bolt pattern

All the small bolt bores should be the same disc or drum front or rear. I have some of those rotors I will find them and get a true measurement a little later.

Edit:
Looks like mcodecuda has it measured all ready
