I need some info to order the stock bottom rail for my savage 110ba

[Alohaalex]

Guys, I just bought the accu-shot monopod B12 and I thought it was going to come with the rail but I was wrong.
i would like to know what type of rails will fit on the bottom of the original stock (screw hole are between 2" apart) And the screws size I will need.
thanks!
