I'm looking to clean out my diffs over the winter and replace the gear oil with Royal Purple. Has anyone used these LubeLocker gaskets? I understand they work well with aftermarket cast type covers. My supplier doesn't stock them so I'm also looking for a Canadian retailer.
I've got some 9" ones sitting here waiting for the next time the 3rds come out. Hoping it makes it easier to line things up for re install cause its a PITA lining them up with RTV smearing around if it doesn't set on perfect the first time
