I am about to build the rear brakes on a 67 gmc c2500 3/4 ton. The rear brakes, nor emergency brake cables etc... do not exist on the truck so this thread has been very helpful. Thank you so much for posting the link to the "Brake Drum Assembly How to" it is for a 6 bolt hub but the setup is the same as the 8 bolt floating hub from what I can tell.
