Your pretty much going to be forced in using grade 8, 7/16 x 20, x 1 3/4 inch bolts, in mounting your calipers to the spindles.Factory shoulder bolts are obsolete, unobtanium, dinosaur eggs, hens teeth, to obtain in this day and age.You, and others, ask about wanting them all the time, with none to come up for sale.
