O.k. might be a stupid question. I have a welded front end in an 85' runner, 4 cyl. A friend of mine, running 36' Iroks testing in his yard blew up a birf just by looking at it with the same set up. As a result, I am thinking that that is not the way to go. I eventually want to replace both with lockers, but $$$$ is an issue right now. Will the carrier for the front axle swap out with the carrier of the rear axle? They are both 4 cyl. axles and that would give me a welded rear and an open front which I could get by with for the time being. Any help would be appreciated.
