There is a gunsmith in Birmingham. Marks Outdoors just North of River Chase mall on highway 31 (Montgomery highway). The gunsmiths name is Russ. I use to work there as a gunsmith myself.
Tell him Kerry sent you there but not to hold that against you.

Russ is a good guy.
You will likely have to have them drilled out to 8-40 threads instead of the standard 6-48 if you stripped out the original mount holes.
