66 Dart trans swap question

I have been reading a lot trans talk. I came here since the early As are a bit unique. Car is a center console 904 auto. IF I went a different route on this car and wanted 927, I understand it will fit other than the pinch weld at the mouth of the tunnel will need addressing.

Will the same shifter and current 904 linkage work with a 927?

What of cross member?

And I assume a new driveline is needed for I do this, it will be because I would be adding power and the current driveline and 7.25 rear would not handle it…thank you
