Ahh Napa! Got one of those a block away... It was a brand new GM dealership till GM pulled the franchise. I will check there, maybe they have the filters and the 12mm hex key. Lol, not too sure what's up with Canadian Tire, usually I find what I need there and it's my closest big chain store that sells tools and such. Well, other than Wally's world, but they don't really have much in the way of tools at all
