SA 17. Weld on disc brake brackets. These brackets are designed to weld onto rear axle housings for rear disc brake conversions. The brackets are made from 3/8" steel, and are cut at a height to use 5 or 6 lug rotors on a 3.125" tube. They will work on other tube sizes with a little grinding. They fit the standard chevy front calipers that everybody uses. (72-87 chevy 1/2 ton and 3/4 ton 4x4) These brackets are sold seperately and in pairs.
For ease of allignment for welding, clamp these brackets to your rotor with a 3/4" spacer between the two. Install the caliper pins without the caliper. Keep the caliper pins just off the top of the rotor. Do not allow more than 1/8" gap between the caliper bolt and the top of the rotor (Two pennies can work good for a guage) Once the mount is alligned, simply weld it on!
