Hey tour bikers....

I'm trying to finish up installing a front bumper to my EG Standard,but am missing the final lock nut for the front tab (it's for the bolt the middle, hanging down inside, under the front fender lens assembly)

-Does anyone know the size of the darn thing? I'm thinking it's ametric bolt protuding down, as I've tried everything in my arsenal - - either too small or too big!

Thanks in advance!

 

anyone with a front bumper bored enough to go out in the garage and check, or better yet, have a diagram from a shop manual?

 

THANKS FOR THE PM SOOS!!!
