Rear End Gears

I was planning on going with a 65 833 in my 65 Dart; however, leg problems are making me go to an automatic. I have a completely rebuilt A500 which I’ll be using. First gear ratio is 2.74 with the OD ratio being .79 (I think). So what readily available 8.75 rear end gears would you use? I’m leaning towards 3.55s based on how they work in my 93 Dakota with the OD and LU A500. How about 3.23’s. Any and all comments appreciated
