Auto-Gem Mounting problem
I have some Auto-Gem signals that I'm trying to mount but, the stalks on the lights are just long enough to be flush on the inside of the fender. Any thoughts on how to remedy this?

Need a little more info.
What is the diameter of the threaded section??
Where are you putting them and on what machine??
Through the struts?? Do you have strut covers on??
etc............

The light is one solid piece of metal. The stalk is part of the light housing. I'm not sure of the diameter of the threaded area. The arrow is pointing to a hole (I know you can't see it but, it's there.) The hole is the correct size for the threaded area but when I put it in, it is flush on the inside of the fender so I can't get a nut on it.

If the housing is a single, cast piece of metal (and not two halves joined together) then the only way the threaded rod can be attached is to be threaded into the housing. What goes in comes out.
My first try would be to put two nuts on the end of the threaded rod jammed against each other then carefully but firmly attempt to screw the rod out. If that works all you have to do is hit the hardware store for a same-sized threaded hollow rod and cut it long enough to get a nut onto inside the fender.

I'm looking at the light now, the stalk is part of the main body and not screwed in. They used a die to put the threads on.

Wow! Seems strange but okay. In that case the only idea that comes to mind is to get a piece of internally threaded rod to put over the existing stalk and then thread another stalk into the end, extending it so its long enough. Might require drilling out the strut covers and fender to clear the new piece.
Might be able to mitigate the drilling by cutting the existing stalk shorter so the new bridge piece doesn't have to go into the strut cover, but I couldn't say without being there.
One other idea, but seems like a long shot. If you could find a t-nut with the proper threading you might be able to use it. The t-nut would go from the inside of the fender out, catching the stalk. Again, might have to drill the holes out for clearance but most t-nuts are fairly thin.

With the internal threaded I would have to use a large headed screw and washers which could pose a clearance issue with the tire.
I'm not sure what you're saying with the second idea.
The T-Nut could be possible. I'll try that one out.
