i'm working on the final assembly of my early 1g gearset trans..i will be using the larger 5th syncro/slider assembly from a92+ trans..what I have found is the early roll pin hole does not line up with the larger steel 5th shift fork!...so i have the later rail that goes with the larger 5th and the roll pin lines up for the fork but!..the "flag" at the selector is hitting the rail!...should i "clearance" grind the flag ??
