If this was on the front you would have a basically minor job.
if both the bad studs were on one rear axle then the job would just be a major PITA.
but since you have one stud on each rear axle that needs replacing, your job is now one of the worst PITA tasks a Pantera owner can face
you will be disconnecting both of your half shafts, removing both of your uprights, disassembling both of your uprights, hopefully finding your axles are still within tolerance, likely replacing bearings and then reassembling everything
all of this is necessary to get to the back of the wheel studs that need replacing.
sorry……
