What bolts were used to mount a 1914 coil box? The 4 holes in mine are 1/4" round. Seems like they would be square for a carriage bolt like the later ones. I just used regular bolts, I guess that's right? I need to take it off and paint it since it's the only thing not painted and the first thing you see and want to get the right bolts.
