I have a 1966 FJ40 with a F engine 3 speed on the tree and vacuum shift assembly. I wanted to get away from the vacuum shift and go with floor shift. I ran into a good deal on a 1975 FJ40 4 speed with transfer case and bell housing. I was told that I just need to change the bell housing and lengthen or shorten the drive lines. The more I read I understand that I can stick with the original flywheel or I can use a F2 flywheel and I can use the type of clutch for the different flywheels.
I am beginning to think I would be better off to swap the vacuum module on the transfer case to the floor shifter type and call it a day.
I do see that the 4 speed housing is 3 inches longer than the 3 speed the transfer cases seem to be the same length.
Does anybody know what items need changed if I go with the 1975 4 speed? Flywheel, Clutch, drive lines.
