Original late 1960s early 1970s Chevy crank pulley for a car with power steering and air conditioning (3 groove). Was blasted and cleaned, but never installed. Used from an original engine. I am told it came off a 1970 Impala 350 but cannot say for sure. No part number stamped in but looks like it matches the 3971280cf pulley. Sold as is, please see photos
