Just an update on my mission to add 6 lug disc brakes to my 1 ton pickup. I located a 1/2 ton axle and spindles to compare to my 1 ton pieces. If my photos decide to upload it will be much easier to see. There is a lot of similarities between the spindles. The backing plate mounting bolt spacing is identical. Upper bolts are 7/16" and lower bolts are 1/2" on both. The spacing between upper and lower kingpin bosses on the spindles are the same. E ven though the 1 ton spindle uses a larger diameter kingpin the kingpin bore in the 1/2 ton spindle is slightly larger than the 1 ton spindle. Probably due to the thicker floating bushing. About the only thing needed to make a direct swap of the 1/2 ton spindle to the 1 ton axle would be a slightly larger OD bushing to accommodate the ! ton kingpin. Clear as mud?
