I really hate to ask this, but the 20 YO salvage cranks I'm putting on the Grocery Getter came off a bottom bracket that used nuts instead of the bolts used on today's available bottom brackets, like the one I brought home from PCF with the last of my birthday money. I had to buy a new BB because the old one was not rebuildable, so now I have no way to hold the cranks to the BB. I'm not looking for anything fancy, just some used crank bolts so I can get the Grocery Getter back on the road. I have some BioPace chainrings I can use as barter material.
