OBS to Superduty caliper upgrade?

Hey y'all,

So had my right front caliper lock up and eat a pad and tear up the rotor. So in my looking to upgrade while replacing, I noticed we don't really have any upgrades to do. So this got me wondering why superduties have option like SSBC and we don't since we all use a D60. Went down to the parts store and had them pull a 97 caliper and a 99. A quick side by side comparison shows the mounting brackets look the same. Not sure if bolt size and thread are the same though, would need to go back and check again? If I recall our rotor sizes aren't that different either? So other than that the SD use a slide pin type caliper what is stopping me from bolting on a upgraded SD caliper? Any insight y'all have would be great!

No, keep my obs 8x6.5 rotor. The carquest computer says there 8thousands of an inch diffence in rotor diameter. Asking if I can bolt a SD caliper over a OBS rotor.

I'll pick up a caliper and see if it fits. And I'll post back up, went and grabbed a set of SD pads today and the seem to have the exact same arch. Only difference I saw was that the pad material was shorter and a little thinner than OBS but that could just be autozone cheapies.

just a few thoughts
the sd has a massive caliper bracket that bolts to the knuckle and then caliper bolts to that it's all Metric IIRC not sure what the OBS uses or if that impacts you

the SD rotor diameter may effect you ? I have a set in the shed if you need a measurement ? EDIT i see you posted 8 thou that seems
unlikely ?? i thought they were much larger ?? what about thickness I think my rotor has that marked if you need it ?

the valving may be off since the SD has 2 large pistons , just a consideration

good luck it would put a huge damper in the rebuilt sd caliper cores if this works out LOL
