Working on the front end this weekend, and attempting to follow Moses Ludell's instructions to upgrade the spindle / knuckle mating bolts from the stock "outside in" style 7/8" to "inside out" with 1.5" G8 3/8"-24 button head screws. I have new replacement knuckles from Kaiser Willy's that must have been different castings, on the passenger side one I had to die grind out some material to allow for the button heads to seat flush, and on the driver side one I did not. When I bolted everything up for a dry fit and pull test, the driver side won't sweep all the way back (left turn) as the head of one of the bolts hits the axle "ear" (where the kingpin sits). Anyone else hit this snag? I'm not sure I can (or want to) grind the head of the bolt enough to allow for the complete sweep, so about the only thing I can think of to do is to pull the offending button head and screw from the outside in with a shorter bolt at that location.
