More in the southern and western areas? I dunno about in the west, and maybe it's different somewhere like Atlanta, but in the North Georgia/Chattanooga area there's not a W123/W126 to be found in a junkyard that I've ever seen. For years I've been on this board listening to people talk about "Well, just pull a spare banjo bolt from a yard" and things like that with sheer green envy.
I know of three or four others besides mine out on the local roads, but not in the yards.
