wtburke,, i need the size of the 2 bolts that hold the caliper to the caliper adapter. you dont have to remove the caliper adapter to get to the pads,,just the caliper. the pads are then exposed and are held in place by the caliper adapter. again,,this is a '01. 5 3500 4x4 which may be different than the 2500's.
i got a set of torx and the T-45 is too small.
T-47 is too large.
closest thing i have is a 1/4 hex bit which would have to be driven in to work.
here is a pic of the caliper:
