Stock radiator trans cooling line measurement

[Skytrooper]

I need to find out what the stock "center to center" dimension is for a 71 big block's radiator transmission cooling line fittings are. I do not have a stock radiator and I am trying to find out from Inline Tube what dimension they build there lines to, but they said they do not know the dimension. I wonder how they make them if they do not know ? Anyway, I do not have old lines to check if they fit. The car had rubber hoses. I want to put steel lines in, but need to make sure they will match my current radiator.

Thanks
