the jag rear end might not be the way to go unless you like having a 5x108 lug patern and want to run taurus wheels, a toyota irs might be the better choice, better axles, better rear end, mustang lug patern, lighter, needs more fab work, many more plusses, lexus also uses the same rear end, if you want to have chevy lug patern, bo with a bmw rear end swap from a early 90s 5 series or late 80s, it will be a drop out unit like a ford, but has way better geometry for your handling pleasure
