hey all. i am trying to find a limited slip or better yet a locker for my truck (06 dakota). it has the 3.7 v6, 10 bolts underneath and i havent checked the panel yet, but from what i've seen/heard its got the 3.21 axle ratio. i know that some of the stock dodge's come with a limited slip or "anti spin" differential from the factory, but I was hoping to find an aftermarket one. i've got a 1979 17ft seaswirl boat that i need to get up the boat ramp in a few weeks, and would rather not be slipping backwards into the water. (yes it's 2wd). any ideas? thanks ot.
