I'm sure it's been asked before but just have a few quick questions. I got a Savage 111 in 7mm mag and the stock is cracked, so I bought a used hogue stock but my guns got the blind mag and the new stock is for a detachable mag. What all would I need to buy/ replace or is can I just buy a plate. Not sure if it matter but my 111 is pre 2000 with the flat top.
