3 speed question (1 Viewer)

[howardtimber]

My 68' has a vacume TC and i recently acquired some parts vehiles so i have motors and transmissions gallore. I have decided to leave F engine in for now but am putting floor shifter scout power steering and wasngoing to leave in vacume but now that i have newer TC with shifter. Not sure whether to put newer trans with shifter transfer or will the vacume still work. I dont really understand the vacume system. Or should i go ahead and put 4 speed in?? I am going to change to floor shifter either way.
Thanks

you'll need to change the bellhousing also if going 4 speed. and if you have the 4 speed driveshafts you'll need the longer ends of those and use the slip joints from the 3 speed shafts and run them with the slipjoint at the diffs.
