If your car is 74 or earlier, make sure your rear calipers were never replaced with newer ones before trying to crank them down to 130 ft-lbs...nothing worse than reassembling calipers with fresh new paint, new pistons, and o-ring seals then all of a sudden...CRACK
This is totally a guess, but I think the earlier rear calipers only had 1 bleeder based off the bleeding sequence info in my haynes manual
