What size bolts - 350x swinger skid plate

[Gag_Halfront]

My swinger skid plate fell off last time I was out riding. I'm in process of making a new one, but I don't know what size bolts I need. I'm obviously not going to take my trike into the hardware store to test fit different bolts, so if somebody could give me a hint, I'd be much obliged. (Size, pitch, length)

mine was 12mm heads, 8mm 1.25 pitch bolts. Most of the bolts and nuts on your bikes are 10mm 1.25, 12mm 1.25, 8mm 1.25, 6mm 1.0, some of the thumb throttle and small master cylinder tops are 4 or 5mm. The swingarm bolt/front axle is 14mm 1.25 and the axle ends are 20mm 1.5
