Hi Guys
I need som help with technical measures. I want to make a drilling fixture for repairing the head stud thread. The case is a 7R magnesium from a 2,7 liter engine.
Does anyone know the exact measures/specifications of placement and distances between the headstuds + cross measures? I have attached a picture - basically I need the distances marked with red lines. All measures from center of hole

Thanks and have a great new year
Søren
