I purchased the rotor via eBay circa August 2018.
I like using eBay because I can acquire SMP brand parts that way. There are no independent auto parts retailers locally here in Ventura, only chain outlets like O'Reilly, AutoZone, NAPA, and CarQuest. I have been burned by each of them. I've never been burned by an independent retailer selling SMP parts.
(SMP = Standard Motor Products)
