This is a pair of vintage rear brake calipers for a funny car, altered, etc. They were originally on the King & Marshall 1974 Sattelite Funny Car. Looks like they may be Hurst Airheart but they don't say it on them, possibly Halibrand. They are in working order and in excellent condition but I am missing three brake pad pins. I have one original to match up for new ones. These are in great condition and would be excellent for a period correct vintage restoration and they can still be used. Hard to find. You may call me with any questions. Ray (401)226-3278.
