Large shank changeover...

[Any Cal.]

Hi all, I am changing a .375 Ruger to a large shank 308. What are the minimum parts I need for the change, aside from the bolt head? Any inexpensive recommended parts to make it easier the next time around? The mag box will work ok I think, if not will single feed for now.

Thanks.

bolt head and barrel and you are good to go.
