Trophy Hunter 111 rebuild 6.5X284

I posted in the wrong area so i'm re-posting.

I have a 6.5X284 norma, Savage 111 trophy XP; I bought a drop in HS precision stock and a Shilen drop-in barrel and a new barrel nut and a new recoil lug.

I want them to work, as of now it won't because the gun I bought has a plastic stock that the detach mag seats into and the mag release is built into the stock.

So basically do I need to buy a frame plate for a long action and rear and front pillars I also need to buy trigger guard with the release built in to the trigger guard and a mag that'll fit the new frame plate/bottom metal that is a 6.5X284 Norma.

Will it work with that action. So basically all as I have is the old receiver and bolt.

I did get one response in the other forum= thanks jm
