Babyface, have you fitted them yet? How's the stock 5th with only 3&4 replaced? Was thinking of replacing only 3rd & 4th. What do you guys think? The car is used in quarter mile but I also use it on the road and I would like some good, 'quiet' cruising. Also, about the synchros, I have just changed them about a year ago, don't think they'll need to be replaced again right?
