I have rebuilt the left and right window frames on the 1950 truck, and have installed the glass with tape, now comes the put it together question. The frame wraps around the glass and attaches to the straight piece on the bottom with little nuts/bolts that hold the frame together. They are like little nesting nut and bolt set (I don't even know what they are called). They did not survive disassembly, and I have not been able to find replacements or alternatives. Anyone find them, or have alternatives?

Thanks
