Hi all. I posted this in the Southeast section but no one has replied. I have afriend with a 99 Cobra with all the bolt ons, 3.73 and a Pro-Charger. He blew his rear the other day really bad and will need to replace it. We were talking about maybe replacing it with a 9 inch and ditching the independant rear suspension. Can this be done and how much work is involved. Thanks for any info.
