Get a ford explorer 8.8 and shorten the LH tube use 2 RH axles. These things come with good gear ratios, a mopar large 5 bolt 4.50" bolt pattern with 1/2" RH studs, are all SAE thread, use rear discs, and most have a limited slip. They all have 31 spline truck axles. The bonus they are all over the junkyards. You can prob get one for $125. Theres a sticky in the drivetrain section on all the swapperoo for this. First page at the top for the 8.8 swap. Even parts like brake discs are cheap. I got raybestos rotors for $15 each at rockauto. Look for the tag on the diff cover with the ratio you want. Example a 3.73. If the diff is a limited slip, the tag will read 3L73. If it's an open rear it will read 3 73. With a space and no L. When you narrow the long end to center the punkin it ends up being only 3/4" shorter than a stock mopar 8.75" axle. I put a bunch of info in there on that swap, including brake cables that are mopar in the front ford in the back. Only thing you need to for sure check is the build date in the door jamb. The disc calipers and pads change somewhere around march / april 1999 to a different design.
