just get a set of stud mounted crane gold rollers....cheap and good quality ....cheaper than the shitty mace so called high ratio rockers for the 3.8 6banger
i MUCH prefer the adjustment in stud mounts. had nothing but problems getting my shaft mounts adjusted properley. getting the allen key to stay in the rocker tip while its flapping back and forth and spraying you with hot oil is just fkn annoying.
