I bought an extra coil for my Vaquero and wanted to mount it on it's own lower rod. When I started looking for a tesoro rod I discovered they're getting harder to find. So I thought any manufacture's lower rod would do and bought one for a Garrett (was the cheapest I could find). Much to my surprise the Garrett rod is slightly larger in diameter and wouldn't slide into the Tesoro middle rod. So, is there another brand I should look for that is compatible with Tesoro, or do I just reduce the diameter of the Garrett rod to make it fit?
