PUMP, A.I.R. / Smog, Rebuilt
The rebuilt pump assembly was an exact fit for my 1972 Buick GS 455. The part appears to be of high quality and was a quick install with the exception of needing to run a tap through the pulley mounting bolt holes to clean some paint or other contaminants out of the threads - not uncommon with a remanufactured unit.
