I bought the Schumaker mounts but haven't mounted them yet. Grade 8 hardware, powdercoated brackets and poly spool bushings. Probably the last mounts you would buy for $150 + shipping. I got mine at Carlisle, $140.
Make sure when you install them that you slop some blue loctite on them. The bolts they sent with mine seemed slightly to short so I had a tough time getting them tightened up with lock washers so had to leave them out on 2 of the bolts, found one missing a few weeks later (nut that is) so loctited them when I put another nut back on and was also able to get a lock washer back under one of them I couldnt before, but still used the loctite just to be sure.
