Where do I start....?

Well, SEMPER FI at ya, Marine! And there's lots worse places than Okinawa! I think maybe the parents could search for that 8.75 rear, have the 360 built by a MOPAR fanatic mechanic and the same for the 904. You will DEFINITELY need to dump the 9" brakes and replace the torsion bars with some 1" or bigger ones. Or, the RMS setup will solve the front end probs. The 8.75 should have 10" drums or disks. I know you love your parents and vice versa, but you'll do better doing the bodywork and assembly parts yourself. Coming home to find the car and the mechanical parts waiting for ya would be the cherry on top!

But FIRST - - be damn sure you come home! All the best to you and yours.
