I’ve got a 70 series drum rear parking brake axle I’ve swapped into my 40 that I’m unsure of the year on. Trying to order custom drive shafts. Anyone have 70 series pinion flange information specifically length and width from center of hole to center of hole and bolt diameter ? I’m getting a 90mm x 90mm reading for COH to COH and 11mm for the bolt diameter with a caliper, can anyone confirm these measurements? Year and model approximation of the axle might help as well. Attaching pics below. Any help is appreciated, thanks.
