So I have a 1968 mustang with the 200ci 6 cylinder and the stock rear end and I'm currently in the process of getting all the parts for a 302 swap and I found a 1998 ford explorer with the 8.8 inch rear end with 373 gearing and Limited slip. And I wanted to know how hard would it be to swap? What would I need to do to make it work? And does it have to be narrowed? Any help is greatly appreciated.
