I measured the thickness of the boss that mounts the spindles, and it is about 2 and 3/8 inches. The kingpin bore is .813.

They probably left the axle stock and just modified the spindles to make them fit, but you will want to check just in case they bored the hole in the axles oversized, or something.

Hope this helps, and sorry I forgot to get this for you sooner.
