The Granada rear end will bolt in. As mentioned, if it is a 9" even without disc brakes, would be a good add on to your Mustang. You'll need the shock mounts from the Granada as well. If it has a rear sway, that would be something to keep. Also the front rotors and disc brakes can be used on the Mustang II as well, it will give you 5 lug wheels, and the option to go with either 14 or 15" wheels/tires. The engine will work, but I think the tranny bellhousing/flexplate are different due to the small one used on the Mustang II, but most of them are changeable. It would not be a problem if you did modifications to the Granada engine/trans for future use in your Stang, it'll all work.
