1966 valiant worth getting a 230 (or 240 can’t remember the numbers)

I just used a Duster hump in my 65 Valiant. Different than the OEM 65 hump, but close enough to be usable. I had no problem with either the 230 or 4 speed trannies hitting the crossmember or the bolts lining up. Never occurred to me to try to make a column shifter work with either trans. Guess I'm not as creative as some.
