3 speed to 4 speed conversion
Hello everyone! I am wondering if anyone has ever converted a 3 speed manual tranny over to a 4 speed manual? (I am working on a 1964 with a 327 3 speed on the floor) My concerns are if I have to change the or modify the crossmember? Driveshaft? Rear end gears? Bellhousing? I am just toying with the idea and do not want to do anything that could not be easily switched back, it's a very original car, but the un-synched 3 speed sucks sometimes. THANKS for any input!!!
