This fit my 94 caprice wagon perfectly. Rides smooth with no vibration. Would definitely recommend versus buying the auto part store stuff!

Drums did not work. The center hole, which centers the drum on the axle, was oversized by .025". This resulted in imbalance causing vibration at all speeds above 25 mph. Amazon accepted return of both drums.
