I have a '54 Chevy that I would like to upgrade to IFS. A friend of mine has a mid-80's Mustang II that he will donate to my cause. I would like to buy a pre-fab crossmember and weld onto the frame. I have two questions: (1) can I use the remaining parts from the Mustang II and attach to the new crossmember and supports? I would like to avoid having to purchase a whole new front end. (2) Can the rear differential from the Mustang be swapped into the Chevy? Any advice is always appreciated!
