With the help of JCLAY's tutorial on brakes, and the watchful eye of a mentor I successfully swapped the rear brakes out! Woohoo!!
On the other hand, the knuckle fell off the end of the throttle cable at the pedal, and it frayed some when we pushed it through the firewall and got a new one on. Car runs, but throttle is hanging up at about 1500 RPM. I noticed some slack in it, so will try and get some "shims" in there and see if that fixes it. Not sure if fabricating a new one (F/I cables are NLA) is something I want to try, as my back really doesn't handle the under dash work too well any more.
