Word of advice; as you rebuild the rear brakes and go to bleed, lift the rear of the truck until the upper wheel cylinder bleeder is in the 12:00 position. As it sits normally, the inner cup of the upper wheel cylinder will sit higher than the bleed screw and you wont get all the air out. Also there is a leading and trailing shoe so ensure the shoes are properly installed.
Did you manage to track down a booster yet?
