I have received the reply from B&C look like I need a Mauser/Interarms MK X, Sporter Style.

Here's the reply from them:

Mauser 98 possibly fits the following but may require bedding:
Mauser 98 Browning Safari
FN Parker Hale 1200
Santa Barbara FN Browning Supreme
Centurian Carl Gustav
Rem 798 w/Side Safety Huskqvarna

Our stocks fit only the SPORTERIZED German & American Actions.
DOES NOT FIT MILITARY ACTIONS.
MILITARY ACTIONS HAVE A DIFFERENT BARREL STYLE AND FLOORPLATE

Our stocks do not fit the Timney adjustable trigger without MAJOR modifications.

All of the stocks listed below use a floorplate and not a blind magazine.

If your stock has a 1 3/8” front receiver ring and is 7 7/8” center to center on the trigger guard screws with a bolt safety you have a Mauser 98. We offer the Varmint Tactical w/ block 2948 and Medalist 2193. Overall length of floorplate is 8 1/2". Width of the mag is: Front .910 & back 1.100.

If your stock has these dimensions, with a side safety and adjustable trigger, you have a Interarms Mark X. The Medalist 2197 is the stock you need. Width of the mag is: Front .910 & back 1.100.
When using a bolt shroud safety on an Interarms, use a 2193

If your stock has a front ring 1 1/4" and from center of screw to center of screw on the trigger guard screws is 7 5/8" your action will fit our Mauser 96 stocks. That stock is the Medalist 2194.

-Our stocks are for the step barrel.
-Stock weights are approximately 2.34 pounds
