Based on the fact that the burb running board / fender interface is identical to the pickup interface and that the running board mounts / parts are interchangeable between burbs and pickups . . . I would say they are identical. I am going to use the either stock 15x5 rims or 16x5 rims . . . so I should have a little more clearance than your picture shows. The comments on the axles came from wrecking yard guys. There is a yard in the closest town that has racks of axles, next weekend I am going to run up there and do some comparing.
