its a little more involved than that. The FV has a blind mag, so you need a mag of course, but also the parts that hold it. Some of the bottom metal is also
replaced as well. I see a kit sold for this purpose, but it is around 209.00 last time I looked. I thought from the post I referred to, maybe Savage had all the needed parts for less...looking at the conversion set, it looks like a flat piece of bottom metal, it has a trigger guard and small lever in front of it I assume is the mag release, then a box that the mag would go in.

It seems there are two different sets, one for stagger feed and one for center feed, which mine is.
