Wiper Post Location

[PaulW]

I am getting ready to drill the body for my wiper posts. I have the measurements for locating them side to side on the body. What I don't have is the set back measurements from the hood opening. I bought my wipers off a forum member and there is no drilling jig. Coutting the holes to the oval shape after drilling a centre hole should be easy enough but does anyone know the hood set back measurements. I have a Mark 4.

Thanks:confused:
