    It appears to be a standard A caliper, but I want to see the fluid inlet side first.

    I believe that is an A caliper that replaced the aluminum S caliper in 1974 on many 911

    I measured some A calipers I have siting around, these have a spacer that is 6 or 7mm, not the 10mm shown. Possible these are later, like from a 84-89 Carrera with thicker rotors?

    Yes, you are probably correct, I was thinking of the 10mm spacers on the 911 rear, but the 911 front with 20mm rotors use 7mm spacers. This is a wide A caliper then.

    I remeasured the spacer and it is 7mm, in the photo the '10' is to the left of the actual line, seems like they are for 74-83
    Thanks for the info guys, so they will not work for me : (

    So since these calipers will not work for me, I will put them up for sale but I would like to know approximately what this pair are worth.
    They are from Stoddard
