The Stovebolt Site Forums The Shop Area Driveline 3600 rear brakes drums 12"

So I'm trying to buy brake pads. Yet my drums measure 12" and have 8 lugs

So the young lady at a major parts house says they have 11" and 13" . Now she did seen new and was referencing their catalogs. So I believe what she said.

This is for a 52 3600. Yet my brake drums seem odd. Rear end # KGp02
