Transmission question

I’m replacing my trans and need to know the input shaft size and spline count. I have a 66 f100 with the 352 and original Ford syncro 3 speed. Going to a 4 speed top loader.

thanks in advance!

Should be the big ten spline. Don't know the size exactly but it is pretty universal in these years.
