Were they fairly interchangeable back then or is it a can of worms?
Thanks,
Dave

Same length as the 3-speed. You would need the 4-speed forward u-joint yoke and the 3-speed rear u-joint yoke.
The speedometer drive and driven gears would most likely not give the correct speed. A ratio adapter can be obtained for about $100 or less.
