They reason the Dana is more popular than the Ford 9 inch is because this is a MOPAR site. LOL. I've had all three (8 3/4, Dana and Ford 9 inch) and currently have 2 Dana's and one 9 inch and I wish all three were 9 inches and may be someday. Build a nice 9 inch and don't look back. If I was starting from new I would probably at least order a fab housing and go from there but price it out for a complete unit and you may save money.
