This thread may be of some help. It has links to reproductions of the instructions for the Zane jig and the carpenter square method, as well as measurements of Zane's jig if you want to make your own.
Somewhere at one time I had read there is a mark on some 8n top covers. Turns out mine has it. It saves the trouble of measuring if you use the carpenter square method. The mark is a circle stamped into the gasket surface on both sides where the ball at the end of the control arm is supposed to be when making the adjustments. The circle is the same size as the ball. If you are lucky and have those marks then easy peasy:-)
