I would assume they are ATE calipers being a '73. I have some but wouldn't put them in the "near new or VGC" category. I just had my calipers overhauled, it cost about $135 per caliper for the fronts and $80 each for rears. I am also out of '73 tail light lenses. Also remember there are 2 different late 140/160 - early 240 tail light lenses. They look the same but are not interchangeable.
I am not sure but Angus may have some?
thank you for your feed back rob and yes ATE calipers i did forget to mention that, i have now found what i need cheers
