I'm considering an A 500 4 speed overdrive for a 72 Duster

No floorpan/trans tunnel work involved with putting a 200-4R in my '69 Dart.
The gear spread is 2.74/1.57/1.00/0.67. I'm going to be running 4.30 gears out back, but it'll be like having 2.88s when in overdrive.

I thought I remembered you did one, I wasn't sure. Did you do a build thread?
