Depends on how much you want to spend. You could get the shift drum with the bearing mod from WCR. Also as mentioned, shift star, shift shaft mod, bushing for the spring that goes on the eccentric screw adjustment. New bushing for your idler gear ect.. Check your basket for wear and tear, if its grooved real bad, get ahold of FAST and order a billet one. Check your inner and outer clutch hubs for wear. Its a good idea to replace those anyways since they are only $55 bucks for the pair. Pancake bearing is a good idea as well. That would pretty much do all the tricks to your trans, unless you want a duneable!!!
