I noticed you posted another pic of your axle in another thread. are you trying to determine if your Jeep has a Dana 44? the Dana 35's have a rubber fill plug and the Dana 44's have an actual threaded fill plug. Hope that helps.
There's no way, *no* way that you came from *my* loins. Soon as I get home, first thing I'm gonna do is punch yo mamma in da mouth!
