Here is the new design, stronger with the elimination of the use of spacers, lighter for the same reason, and still 3/8" thick for strength and rigidity and it cost less to make so it costs you less! These are for a 14 Bolt housing and use 3/4 ton Chevy Calipers (not included), no extra mounting hardware needed. They fit both the Full Floaters and the Semi Floaters, they have the same spacing. These also fit the Eaton axles (pre metric) Sold as pairs. These brackets are a must for a disk brake conversion!
