Do it, you'll love it.
My Dodge dealer wanted $1200 plus installation for the limited slip. I purchased the same item aftermarket for
$300 but that was a few years back. Try Reider Racing or equiv. I don't think there are any "lockers" for the older Raider/Monty's, just LSD's You might check with LLoyd Swartz.
