where in wa are you located?
The bolt shank going thru knuckle must fit snugly, and must go in from inside out, like your oem app. Make sure bolt shank and knuckle holes are very close to same size. I would think just a couple of 0.001" or so. You don't want a lot of slop there, certainly not the threaded end, because that would be too much slop. Maybe you can find a smaller hex nut with 1/2 x20 thread. Maybe a 12pt nut. I don't know for a fact, but I should think they should be gr8 fasteners.
