Hey All,I am restoring a 66 chevy C10 short Fleetside and having one hell of a time with the drum brakes… cannot find the correct drums to fit… should have switched to disc brakes on the rear but didn't..Can anyone tell me what year my rear end is?? i don't know if it has beed changed or replaced, the truck had a 350 with an automatic in it when i found it, it has a welded hole in the floor from having a manual tranny, so someone has done some changes.It is a 6 lug, i do know it is not a posi...I have found the following things stamped on the axel:HA 01 04I also found a D closer to the wheelAnd on the the housing.GM163856525A116Any help would be greatly appreciated, i have purchased the drums for a 66 and drums for a 80…the 66 don't fit over the pads and the one for the 80 fits but it locks up once the lugs are tight…it hits in several places on the hub.Thanks!Robby
was told by a guy today that he thought it may be out of a 72-72 4x4… any thoughts??
Is the problem you are having, the 66 drum will not fit over the brake shoes? Make sure that you: #1 make sure the park barke cable is completely released, arm all of the way back. #2 make sure the "Star" adjustor is spinning freely and can be screwed all of the way in to the shortest effective length. This allows the shoes to reduce to the samllest diameter. I always disassemble the adjuster, clean threads on a wire wheel, then lube with high temp brake lube as I screw it back in to full seated position (Shortest). The knock-out on the drum can be removed (Some are on backing plate), but this allows you to use a brake spoon to adjust the shoes up to almost contact the drum.Check park cables to see if they are rusted stuck inside the housing.Best of luck.
