Mopar 8 3/4 or Ford 9?

We could go on and on between the ford or mopar rearends, but it comes down to personal preference. Use what you want/can afford. Some like to use all of the big 3 makers drive train, some like to use a mix, do what you feel like. Just keep in mind that some people may look "down", on the "brand x" rear, but you can say you did it your way and that is all that matters.
