[amsat-bb] Yaesu 5500 rotor question

I had a 5500 azmith rotator lockup over winter. I finally had time to take it down and find the problem. Now a different problem. I forgot to mark the housing position before separating the upper/lower azmith assemblies. I think I know where it was pointed, but how can I tell where it should be aligned? Is this really a non issue?
