Universe/ RG-7 measurement????

[Jemmm]

Based on following pic, I'm making a template for RG-7 headstock.
Could someone grab their RG-7/Universe and help me with following measurements. Thanks.

According to my RG7620 headstock , A = 5 and 5/8 inches from the center of each string post . B = 7 and 1/8 inches , compensating for the rounded points at each end .
Those are exact measurements , not guesstimations . Hope this helps .

Thanks. I already scaled pic so nut would be 48mm, also compaired measurements with my RG-6......but it's always handy to compair to regular RG-7.
