If you decide to use a gasket, you need one for a Dana 44 rear end. They're pretty common. Ask for a differential gasket for a 1967 Jeep CJ-5. Here's a link to the one you need from RockAuto. https://www.rockauto.com/en/moreinfo...381238&jsn=892

Really if you're wondering how your Powr-Lok is doing, check the breakaway torque. Here's a thread on it: Breakaway Torque on ERA's Powr-Lok If the breakaway torque is within specs, and you don't have puddles under your differential, and when you drain your fluid you don't see glistening specs of metal in there, then practice the LITFA rule.

Or the "enhanced LITFA rule," which calls for parking the car in the sun and then you LITFA.

I just went through this whole exercise and could not find the correct gasket to order. Tried NAPA, Auto-zone and a few foreign car part places. First you need to know what type of rear end. Salisbury or Dana ? After I determined it was a Salisbury, still no luck so I finally gave up and used Permatex Black Max. Worked great and no leaks for the first time in 15 years!

CJ5 about 1975, diff gasket will fit both Jag variants in ERA.

Telling the parts guy it is a Jag will just make it hard.
