 Looking to replace the studs in my 8.75 rear and Summit has ARP 100-7705  with a 680 knurl which says its for Chrysler rear brake applications which seems large doesn't it ?

Check these out, I would measure yours but should be ok.

 Thanks,  I'll have to get a caliper and check them. I stuck a 615 stud in it and it "almost" fit.

     Is the number  685 is that (thousandths) ?

I believe the use of those .680"-.685" knurls is predicated on wallowed out stud holes, might be too big for the standard holes which, I believe, are closer to .665".
