Measure the inside of the ram bores where the bushes are to fit you will need 0.002" to 0.0025" (0.05 to 0.06mm) interference on the bush, just be aware that the bush could close in a little so if you have a reamer that is good; I prefer the adjustable reamers myself, worst case scenario use a flapwheel on a drill but be careful not to make the new bush oval.
