The first three are from 1973-82 vintage. I don't know what the 4th one is; perhaps an aftermarket casting.

Some rebuilders like Lonestar Caliper and Vette Brakes will sell you a set of original casting number calipers (for an extra charge). All of your caliper halves should have casting numbers beginning with "546".
