Good place for rare gun parts?

I need a guide rod for a Wyoming arms 40 with a 3 3/8 inch barrel (very rare) or someone who can make one. I have an idea on how to make a better guide rod if I had the parts. So if anyone can make one or know were I can have one made, or maybe find an original it would be very helpful. Thanks.

Numrich for a replacement part?

Definitly Numrich.
