Used pair of 1962 Cadillac 3-groove a/c harmonic balancer and water pump pulleys. I believe these are the same pulleys used from 1958 all the way to 1967 on 365 390 and 429 Cadillac engines. Buyers please be certain but that is what my research shows. Cleaned, blasted and painted. Some minimal pitting from rust. Includes the reinforcing ring and bolts to mount the lower pulley to the balancer.
