The front seems to be Chevrolet, and has one adjuster independent of the cylinder located at the bottom of the shoe and the backing plate has 1 opening for adjustment. The rear has 2 slots for adjustment at the top of the backing plate and the backing plate is fixed to the diff. housing with rivets. That is why I think it is a GMC diff assy.
So do you think I am correct about the springs being installed back wards?
