Yes, I looked at some images of Expy steering wheels, they are of course like any other Ford wheel, only go on one way, as I'd figured they would.
OP, you're on the right track. Get it in the ballpark, replace whatever broken and worn stuff you see, and then get 'er aligned.
The string method works pretty well if you have a flat level floor. I did it one time on a Fox Tbird, I even used a long level fastened to a piece of 2x4 to get the camber pretty well set. The alignment guy said I had it pretty close that it would've been driveable and not had any adverse tire wear...more luck than skill. On alignments, I'll trust the machine over myself every time.
