OK driveshaft gurus I need some serious help...
We put a 360/727/8.75" in my fathers 1972 Dart Swinger. Car was originally 318/904/7.25". Obviously the driveshaft will no longer fit. (There is a 95% chance the car will be getting a manual gearbox)
1. What is the proper length driveshaft that we need?
2. I was wondering what transmission/drivetrain combos were the same length. (are 904/727/1967-74 B&E-body A-833 4-speeds the same length?)
2. Can we get a factory shaft out of any car to work if we use the shorter A-body 4-speed?
3. Is there any website or info anywhere that states the transmission/rear end/driveshaft length combinations?
Sit down and rea this part a few times. I apologize for being so scattered:
We currently have a 1941 Dodge 2-door sedan that they used the drivetrain from a Plymouth Road Runner (383/4-speed/8.75"/driveshaft). The 383 was replaced with a supercharged 360 but my father is toying with selling the 1941 Dodge and installing the supercharged engine in the 1972 dart and dragging that. If he sells the 1941 Dodge he wants to pull out the 4-speed & 8 3/4" sure-grip rear and stick in the stock 360 from the Dart, either a 3-speed manual transmission or a 904/727 and a smaller 7.25"'/8.25" rear end. He also has a 1972 Dodge Charger SE (318/904/8.25") that will eventually be 440 powered and the 4-speed & sure-grip 8.75" rear (from the 41 Dodge) would be great if the rear will fit right in. I thought these Late model B-body Chargers had a little wider rear than the rest. Is this correct? Will the Road Runner 8.75" rear bolt right in or were the spring perches different? A lsightly narrow rear would be great providing it isn't a bunch of work. If it is too much work than we might as well narrow one down. Other than a 1971-74 8.75" is there an 8.75" rear that will bolt right in?
