904 swap 65 valiant

Your right. My mistake thinking a 65 was still push button.

I haven't even worked on a car with the ball and trunion but if he were to put in a newer trans. can't he just replace the driveshaft with a std. U-joint type?

Sure, but that's another part to find.

Best bet would probably be a '66 MY set up if you could find the trans and 'shaft together.
