I have a 65 Barracuda with a slant 6 - three on the tree want some transmission/engine advice

mmm I like the idea of an A230. Did not know that was an option. What considerations would I need to make for a 65, or feel free to point me to posts that give me hints and I will go do some homework. :) - And yes I tell people I don't need a car alarm as nobody under 40 knows how to steal my car...ha
It's not. Not without the floor modifications I mentioned earlier. If you do that, the A230 will fit. I've tried it. It will not fit otherwise. It's the same basic size as the A833.
