I need 67-70 400/ 455 a/c pulleys. Does anyone out there have a set of 67-70 a/c equipped big block pulleys? It appears my Stage 1 nonair car was supposed to have a/c pulleys. It might be causing it to run hot at idle and low speeds. I need the w/p and crank pulleys. Anyone want to part with some? #'s 1375146 and #1375143. Thanks. Regards, John
