Stock inlet question for ARC action

[.300 Dakota]

I realize the Nucleus has to have an M5 bottom metal inlet, but if the stock is inletted for a Rem 700 drop in, how much work is involved to fit it to the action? I know the difference is that the Rem 700 stock would be set up for a trigger hanger, whereas the Nucleus has none. I didn't know if this would be a big issue or only if the other way around. If this question has been previously answered, please point me to the appropriate thread.

Thanks!
