Rob, the hinge arm is a steel tube but very thick metal. I drilled and tapped in a stainless ball with a threaded body. I am still playing around with the location one the tab. On positioning, I had 'attached' the bottom of strut to the lower chassis rail and then from under the car on the hoist I moved the arm through its arc at the hinge to try to establish a point where it seemed balanced and gave enough force to hold the bonnet up, without pushing it up. I used a small G clamp to try different positions.

The various figures (above) helped but basically some experimentation.
