That is good to hear about the clutch, but I'm not looking to swap engines, I need to swap the transmissions but my thought process is that since the 6 speed has 1 more gear, the transmission will be longer, so the transfer case, the drive shaft and possibly the differentials and drive axels will be different or different lengths so they will need to be swapped as well.
It would quite a relief if all I had to do was swap the actual transmissions, not the other drivetrain parts, save a lot of labour time...
