Updrilled the shoulder belt bracket to 3/8" for the AN6 bolt. Needed a 1/2"ODx3/8"IDx1/4"L bushing for the shoulder belt bracket and couldn't find one in my parts, but found a 1" long one at the hardware store. Initially I cut the bushings to 1/4" long, but found it was too long for the specified AN6-6A bolts. I trimmed the bushings to about .17" which is slightly longer then the belt attachment thickness but the -6A bolt was still too short to get the full engagement of the Nyloc nut. I ended up using a AN6-7A bolt which leaves a couple of threads proturding past the nylon.
