Trigger guard for McMillan stock?

I recently bought a McMillan hunter stock for a centerfeed long action. As it was shipping, I ordered the blind mag box and follower for a 7 Rem Mag. The trigger guard savage sent me doesn’t fit the inlet of the stock. The stock seems to be cut for a flat trigger guard, whereas the one savage sent me is, well, not flat. Can anyone assist me? Is there an “older style” I’m unaware of?

PS: I bought the stock second-hand, but was told it would match my action by the seller.

Did you get a bottom bolt release trigger guard? Here are some examples: http://www.gunshack.com/savage-parts...trigger-guards

If the inlet for the trigger guard is deep you get the new style. If it is shallow the old style. If I remember there may be two different widths. If you have some calipers measure the depth of the inlet near the fron hole and the width somewhere in the middle. I can measure what I have and tell you what you need.
