7 1/4 Gear 2.93/3.23

Hi there: I am looking for a matching ring & pinnion for a 7 1/4 different than 2.76:1. Something numerically higher as 2.93 or 3.23 could work fine for me. I cant find any of these from aftermarket sellers but I do understand these came OEM in cars before 1968. There are no old mopars around here in junkyards and I was wondering if anyone knew where could I get a set of 2.93/3.23. By chance someone have one of these laying around??
