Hello fellow mustang enthusiasts, I have used various mustang forums in the past to answer lots of my mustang build questions, but I have finally come up with a question that I cannot find the answer to in an existing thread. I have a 69 Sportsroof and I have replaced the entire floor along with toe boards, fire wall and frame rails. I am at the point now where I am ready to reattach the front frame rails to the inner floor supports. The front frame rail assembly is complete with shock towers, front fender aprons, and radiator support. The only pieces not installed yet on the front frame assembly are the rear fender aprons (I thought these would be easier to do last). My question is how can I make my car whole again while ensuring that the car will be square and properly aligned? I am thinking about the wheel alignment as well as the fender/door/hood alignment. I would appreciate any suggestions or experience you can share.
