I bought for 500 series but I need 650. I kept (1) 6 arm brush. I am selling the other 7pcs all together. See pic for compatible series. NB VS- I live in SA & work in NB close to HEB Plus/306. I can meet during lunch or a little after 5pm. If those times don t work, lmk. My job is gated but I can arrange pickup with the Security Guard. Thanks!
