So I have decided to go with the manual transmission and use the flywheel that I got. I am going to use the SM420 and a DANA 300... I saw a jeep site that was saying the NP205 was too wide for the frame rails. I have a 1988 Mitsubishi Montero that the MWM is going in and it is just slightly bigger than a samurai so I need all the room I can get. I know the automatic trans is the 4L60E or 4L80E that bolts to MWM, so any help with finding a bellhousing that fits that pattern and that of the SM420 would be a tremendous help!
