help with top installation.

I am installing my top on my 1965 Valiant. I do not have the old top to use as a pattern. This makes it harder and requires a lot of measuring etc. What would help is if someone could measure the distance from the bottom of the sides of the top at the rear window where they meet the chrome moulding to the next snap on the moulding on the window side. My top is for a 65 or 66 so I do not know if other years are the same. This would give me a place to start with that area and I realize I may have to adjust some but I am getting good at that.
