I'm building an English Sports Car and using Mustang II front
suspension. My calipers are rusted beyond repair. Can anyone help me
by identifying what these calipers are from? The yellow one is what I
need to replace. The gray one is what Auto Zone and NAPA advise
belongs on that model. Needless to say, BIG difference. Anyone able
to identify the yellow caliper? Photos under "Jim Seekonk brakes.
