bolt sizes

[Roxaronny]

What are the sizes of bolts that fit the threaded holes in rear “bumper”? SAE or metric?
I’ve been to hardware store twice and guessed wrong both times. 7/16 x 14 is close but slightly too small. Metric equivalents I was given are too big. Help. Thanks.

M8 I believe

M8 is a little smaller than 3/8...m10 is a little larger than 3/8...thread pitch could be 1.25 or1.50....

Just about everything on it should be metric. Numbers on the heads versus hash marks for SAE bolts.

Roxor Service Dept answered my inquiry:
The smaller captive nuts are M8x1.25
The larger ones are M12x1.75
They work; the thread pitch was throwing me.

^^^agreed. M8x1.25 and M12x1.75. It took me 2 times to the hardware store to figure that out.
