Will short target action one piece base fit short Mod 12 action.

They look the same to me but it's hard to tell for sure with scopes mounted on all my actions. ??? Everything I eye up says yes?

I actually swapped my Ken Ferrell one piece base from my Savage 10fp w/accutrigger to my 12 F-t/r and it fit perfectly.
Savage Round Top Short (RTS) bases fit any Round top short action.
