I've been reading about upgrading the gearbox in G60 to the CTN box to give better gear ratio's, and have also been reading about changing the shifting mechanism to the mk4 stuff. However I can't seem to find anything from anyone that has done both changes together. I've found something about changing the shift towers over from the O2A box into the CTN, but that it also needs some modifications making. So would that also need doing if I was to try putting the mk4 shift tower in the CTN box?

Any help is appreciated!
