Hello, I recently acquired a 67 FB 400 4spd and am about to rebuild the diff which is an XG 3.36 open. I would like to replace the internals with a 3.23 (with posi if possible) and since new gears are not available, I am looking for a good used set. My car has ac added and I'd like a little taller gearing for the occasional interstate run. 400 cars with a/c came from factory with 3.23.
Thanks for all the knowledge,
