HELP! Fender rail nut stripped.

Please add this info under your avatar so folks can better respond to your posts.

You have a Roadster = tis the size I posted - 8mm X 1.25 thread X 30mm long.
I mocked everything up. The threaded hole on the bottom mounting bracket does not line up correctly. I used the .250 spacers as specified in the instructions for the roadster models. sds
 
Difficult to follow this with words only.
You be talking about a ½ grommet so I assume this is #6 (on Bike Bandit) and for a forward mount bolt.

This bolt is a 10mm X 1.25 thread X 45mm and NOT an 8mm as previously discussed.
Are we on the same page so far?
 
Do not try to thread those bolts with the seat on. You will strip the thread because things don't line up.
 
The front bolt is an m10 the rear is an m8. I was able to get everything lined up, but am wondering if welded nut on the bracket that attaches to the passenger foot peg should be facing up as per the instructions from corbin. It seems that it would put a lot of stress on a small area.
 

That would only occur if you had a square tyre fitted....

I may be preaching blind to the already converted here - but please note it is a FINE THREAD M10. It 's not the standard ISO.C 1.5mm pitch. Neither is it the 1mm pitch used on many pipe threads - it's 1.25mm (sometimes used as pipe threads - esp on Japanese made brakes - Nissin for example).

Wont be the first(or last?) time I see somebody try and force a coarse bolt into a fine thread or visa versa.
 
I messed up and stripped the threads on the nut that holds the fender rail to the fender. Does anyone know exactly how the nut is held in place?

Maybe the simplest and cheapest solution is to make your own thread tap. Check youtube.
