Have you sorted out a way of doing this yet? I have a Fairbanks Morse mag that was originally mounted in a manner that was not going to hold time for long periods of time. I have seen these mounted a couple ways, but I am not sure which way I want to go.
No matter what I do there is going to be machine work and probably some welding. The hole on my cases are not even round and I am going to have to spend a lot of time trying to find center.
