I'm building some face frame base cabinets for my office and am stumped on how to install the drawer slide hardware where the cabinet side is not flush with the faceframe edge. Do I have to shim out the slides to flush them up to the FF, or do I buy some of these http://www.leevalley.com/en/hardware...614,43616&ap=2? I want nice quality self closing sliders, and some heavy duty ones for the file drawers. I'm hoping someone can point me in the right direction...my eyeballs are falling out from Googling and I need some quick relief

Thanks-
