I ordered an additional drawer for my locker which in theory is quite the simple task. Order the drawer a set of sliders and move some shelves around and wa la install the drawer. I got the wrong sliders. I did not check part number on them just started to install. No go, figured I was being an idiot, turned em every which way and was eyeing the welder, my default position. Through the tequila fog I thought perhaps we should check the stamped number on side of slide and ensure it matches existing sliders prior to welding in the sliders! My now deceased Brother taught me that, his favorite quote was "Brother, step away from the welder" Hah. I miss him. Anyway in my infinite wisdom it appears I ordered the incorrect sliders. I loathe the Snap On web site. It is about as useless as tits on a boar.
