I have both front and real calipers from a 1975 car that has less than 30,000 miles. I tested them to make sure the pistons are not stuck. At a minimum the outer boots boots should be replaced. The adjusters on the rear calipers work. The pistons were a little sticky in retracting. Can get pictures later. Asking $50 for the fronts and $75 for the rears. Flat rate shipping of $10 per pair. If you want both pairs I might be able to get them into a flat rate box for $15.
