For parts contact Southern Gear in Atlanta, they still have new shift forks, the input shaft nut and a shim with an offset in it that goes between input shaft and front bearing. The offset shim allows oil to still get to the front bearing and get a little more spline engagement of input sf/haft into the synchro drum in3rd gear. The owner Kenny is a wealth of knowledge on SM-318's since it was the first transmission they allowed him to rebuild way back in the late sixties.
