I have an 84 that WAS a Dolphin. It has the upgraded 88+ rear axle. I procured the front hubs from an 87 so I would only have to carry 1 type of spare. The new rotor size is 257mm instead of the 247mm original. My problem is the calipers. I ordered the calipers w/ bracket for an 87 1-ton, but the distance between the caliper bracket bolts and the caliper bolts are shorter than the OG non heavy duty brakes. I know they didn't change the spindle. Am I looking at it wrong?
