Actually, Rockler didn't have any on display at the store - I pored through the hinge section for at least half an hour. But I probably could have asked and should have. At the time I just assumed that if they didn't have 'em, my next stop would. Dumb, especially if it turns out they have 'em in the back or something.
I was at Clyde Hardware the other day and no dice there either. I really expected that a hardware specialty store would have them. I even called Clyde in advance and asked for them specifically, but I think whomever I spoke to must have thought I just meant regular hinges. They've certainly got plenty of those. No stop hinges though.
As for WoodCraft, it's my understanding that the Tempe Woodcraft closed up shop some time ago (not sure when). That leaves the WoodCrafts in Tucson as the only ones in the State. Is it just me, or is it strange that Tucson has two of them but the entire Phoenix Metro area has none?
I ended up going with my plan B out of desperation (standard hinge and a fabric cord for a stay). It'll work out okay, I think. I'll just stock up on the little 95 degree bastards next time I see them in person or order from Lee Valley.
Thanks again for all of the suggestions - great to know that there are other Phoenicians on the 'Wreck".
