I just did my 72 blazer sorry no pics. here is the skinny on what i used 73-87 chevy 3/4ton calipers and rotors and afco weld on brakets any circle track mag has got them about $14 and front brake lines frome a 73-87 the only thing is you will lose your emergency brake inless you use a line lock which is what i did.I cut my pads lose.took the drums apart pulled the hub away from the carrier and drove the lug bolts out i slipped the disk on but the lugs back in the hole and put it back on the axle.do the other side.now your ready to put the axle under the truck i left the pads lose and let them lay on the axle and jack it up to meet the spring so you can pitch the rear drive shaft for the best angle. find that and take them next i assembled the brake caliper to the braket. then i put the pads on and used some heavy zip ties to space the set up on top of the rotors this worked very niced as far as telling you where to put your brake as far as towards the back are towards the front i put my in the back but the new chevys have them in the front i dont know which is best but mine work great.the rest is very easy.weld it up and go.You my need a proposioning valve i didnt use one.I see no need for a backing plate also.
