Help save 7 1/4 !!!!

I got this rear end from Scampin (Great Guy to deal with) and now I am going through it so it will not give her any problems in the future. It's a 273 Auto and I am trying to use all of the "UPDATES" I can get off of here (GREAT FORUM) for the Car and it will be more of a "Resto-Rod" I guess you would call it more than a restoration (Backyard kind). Doing all of the Safety updates I can.
