I know what you mean speedbird, when I did my brakes on my '84 Interstate, they were exactly the same.
As travelinmays states, the pins push out from the retainer side, the mushroom is where the retainer sits. This is where you need to be careful, if you flatten the mushrooms, there is no way the pins will come out unless you cut and drill them!
turn the caliper upside down, make a dam and fill the caliper with a penetrating fluid and leave overnight to soak into the pins, see if that helps.
I still think that if they are as bad as mine were, you're going to need to get them pressed out, took 20 tons of force to move mine!!!!
good luck......................:bash:
