I use Raybestos Professional brake components (rotors & pads, drums & shoes)purchased from Rockauto.com. Good quality and price but I always verify price on Amazon. FYI...Rockauto always has a 5% coupon code out there....Buckaroo
Unless someone stole them, why are you replacing the drums? The factory drums are very heavy duty. Take them to an auto parts store like carquest and have them turned on the lathe. They should never wear out with the little use they actually get. It will cost you about $15 each.
