hi i just got a 89 b2 "4x4" the previous owner swapped from manual to a automatic trans. i noticed driving it, it makes a noise as if something was loose under the drivers seat so o looked and does not have the bar that come from the axle to the transfer case connected. not connected at the transfer case. I have no idea what to do and if they did not connect it why would that be. also got ride of seats a rugs to find that the floor is rooted with rust any easy way to fix. i got a friend who suggested i weld a explorer flooring he's got. i really like the truck so any help is welcome...
