65 Dart Transmission Question And Options

Hi.

I'm considering a 65 Dart 270 w/standard tranny. I will be replacing the engine (I think it was originally a slant). Is a floor shifter available (no console necessary) or either 3 or 4 speeds, and if I need to replace that tranny, what can work in it? I'd rather just stay with a stick since it's set up for that. It had a column shift originally.
