At one time i had a 58 chevy 3/4 ton with a 396 and 400 turbo. I made my own column shifter.

I used some small diameter round bar with a bend at the top end, welded an arm at the bottom for the shifter linkage rod. It was real fast and simple, although not very pretty. With a little junk yard looking and a Saturday fabricating, a real nice shifter could be made.
