I installed these rear drums on August 24 th of 2020 and removed them May 14th, 2022 when I converted to rear disc brakes; they have 17,517 km's on them; two drums only, the rest was sold, and are original to my 2000 chevy astro van. Lots of stops left in these drums! If they are listed they are available! On west saanich rd about a km from Wilkinson rd heading towards Brentwood Bay.
