Hy Bigtonka, I did not realise your truck was a one ton, on those mounts, at least the factory ones, on the bottom the outermost edge was rolled/angled up to clear the rising crossmember, perhaps that feature was left out of the repro mount. By the way Anchor Industries still produces that mount, their p/n is 2073, and I can purchase them through my f.l.a.p.s..
