Interesting! I tried to put 74 glass in a 73, holes were in different locations. Tried it again from a 75, same thing! Put all three years glass on top of each other and all three had a couple different locations.

The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
