IME with any Mauser the following has always worked:
1. Glass bed the action in front of the magazine, make sure only the rear of the recoil lug touches the glass. The front, bottom and sides must be free.
2. Glass bed the barrel for 1" in front of the action.
3. Put a dot of glass where the rear tang meets the stock.
4. Make sure the sides of the action are evenly bedded in the wood
5. Ditto the floorplate.
6. Free float the rest of the barrel.
7. Torque the front screw to 40 in lbs, the rear only enough to be snug (otherwise you can bend the action)
None of this is original, the method was invented by Col. Townsend Whelen in the early 60s.
The glass bedding supplies and other bedding materials are available from Brownells 800-741-0015.

Congrats on getting a classic FN and don't let anyone tell you that because it came from Sears it is no good!
