Boring update, but tapped the threads in the track ends. I'll be getting some flanged "button head" bolts to match. The size is M5- this was the closest match to the 4mm holes, though the tap set had a 4.2 mm bit, but this felt like it wasn't tight enough when I was tapping the threads. Next step will be more filing and then finally I'll have to cut off the excess bits of the dropouts-the point of no return, eek!
