Use a 18.432MHz 2 legged crystal. It will operate on its 3rd harmonic, approx 55.25MHz. Of course you need to figure out which of the 4 connections to connect the 2 wire crystal to. Usually, these SAW resonators have a ground lead connecting to its case. Usually tne 2nd lead from one end. Connect the crystal to holes 1 and 3 after removing the resonator.
