Your left and right window glass should be opposites. One thing to look for in the yellow pages is a glass company that's been in business forever. Also, don't restrict your search to automobile glass companies. I found one local building glass man that was able to look at a window glass for my 52 and tell me how it was cut wrong. Walked over to the grinder, worked on it for a couple of minutes and told me no charge. It fit like a glove.
