I have a 208 case I am selling to another member, but I want to make sure this is gonna be ok for him. It looks clean and shifts fine. the case is ok were the shift rail goes in. My only question is, how much slack is supposed to be on chain?? My tranny guy says 1/2 tp 3/4 is good, up to an inch. an inch seems like alot! but this case has about 2/3 play. what do you think?
