I want to convert my 3.55 open rear to the correct (original) 3.23 rear gears (original manual + A/C car) and would like to make it a posi (officially Safe-T-Track but I just use posi as general term) while I'm in there. So far I have found plenty of diffs for up to 3.23 and then the 3.36's and higher, but I'm striking out finding just a set of the 3.23 gears. Am I looking in the wrong places?

Shop manual says one diff for 2.73-3.08 and another for 3.23-4.11, but all current diffs I see online cut over at 3.36?

Any help appreciated! I'd like to get my rpms down some since I'm running the correct Muncie M20 trans. Thanks!
