Your 67 Catalina assuming US built not Canadian. Has gear interchange 1965-1970 Pont B body cars 12 bolt 8.875 ring under a 10 bolt cover 31 spline bolt in axles. Using the 71-76 Yoke (pinion flange) also the some 71-76 Pont B stuff to as I understand ... Hard to find a gear lower than 2.93 in a Safe-T-Track , look for a parts car stick 3 spd-4 speed car or 2+2 for a 3.23 or 3.42 is tough to find, FABCraft Metalworks can help with possibly some new 3.55's not sure if any inventory though.
