You need the A SX configuration, if the A is correct for drop height. 3 components. First plastic plate by the action is A. With the A letter upright and facing the rear. Then the SX plastic plate. SX lettering should be upright and towards the rear. Then the stock goes on. Metal plate should have A and SX upright and facing the back of the stock.

Same set for SBE and SBE II

Midwest gun works sells them seperately
