I some hard to find Stith parts for sale. The parts include the mounting block and split rear ring that fit into the standard aluminum rear mount for the Savage 99. If you are not familiar with the aluminum rear mount for the Savage 99 it is the one with the windage screws. The parts I have will fit into that base and are secured into place with the windage screws that normally hold the one-piece ring in place. I actually have two of the mounting blocks that will go with this sale, however one has a patch of surface rust. The ring and other mounting block are in excellent shape. I am asking $125.00 shipped and please PM me for pictures and questions. Thanks
