I found a few places on line but they sell qty of 100... i only need 16-3/8" weld on floating nut style to mount my body on my chassis
McMaster Carr sells them in packs of 10. http://www.mcmaster.com/#catalog/115/3178/=3fqtsf Scroll down to bottom of page. .
Just make the damned things you rich bastard! Hahaha...some flat steel barstock cut to square nut size, drill and tap, then cut and bend a 16 gauge sheetmetal "cage" around your new nut and there you go...
He sure could do it that way . . . . . . He could also spend the better part of a week building enough of them to put the fenders back on his A too. (and yes, I realize that you were most likely just busting his balls) At some point, every man has to decide how much his time is worth, and act accordingly. I value my time too much to spend it building cage nuts from scratch, when they can be bought readily and inexpensively. A fella could build every nut and bold he needed from scratch, if he were so inclined, but to most of us, it'd be one hell of a waste of time to do so. I'd look at Aircraft Spruce, Fastenal (or as we call it, FastenSome , 'cause it'll be a miracle if they have them), MSC, and Enco too. McMaster has everything in the world, but they're proud of their stuff, so there is usually some place that has the same thing for a little less money. I'd check Aircraft Spruce first, they keep a lot of odd fasteners on hand, and their prices, while not super cheap, are reasonable for aviation hardware.
Good God, with the time you've wasted finding a supplier, ordering them and waiting for them to show up, you could have your fenders mounted by now...you really mean to tell me you'd rather waste a couple days worth of time than a couple hours to make them? Yeah, if I could walk down to Napa and get em cheap right now, I'd do it, but my time is much too valuable to waste sitting around waiting for parts that I can make myself...and it's very good practice in sheetmetal shaping, once you get your pattern for cutting the sheetmetal down and the bending figured out, it goes pretty smooth...
