Does anyone have a source for the grade B7 7/16"-20 threaded rod needed for removing/installing the crank hub? I started looking in local hardware stores this week and I can't even find fine thread rod, let alone something like B7. I checked my local fastenal suppliers online and no one within 100 miles had any on hand, and they only came in a two pack so I'd be looking at about $40. Amazon and ebay were similar. I was about to throw the towel in and just get the old kent moore tool kit, but those have gone way up in price if you can find them. The one complete set on ebay right now is $300, and there was an incomplete set (though I can't really tell what's missing) for $160.
