[1963c-10]

For daily driving,, there is nothing wrong with a muncie or saginaw 3 speed if you want to stay w/a 3 speed manual. My 63 still has the original muncie 3 speed on the colum as did my 2 previous 63's and I have never had a problem with any of them. I never pulled anything or loaded anything that it couldn't handle. Its also easier to replace what you already have in terms of having to modify stuff. If the 3 speed manual will handle what you want it to do, id replace it with the same model and keep driving it. And for what its worth....the saginaw 3 speed has proven itself on many dirt tracks across the US.....it the prefered trans here in the south. So they can take alot of punishment.
