In reply to # 1500494 by Fictioneer I'm thinking there has to be a simpler solution. Some sort of pivoting hinge mounted inboard. Perhaps on the rear portion of the original bracket where it is welded to the front bar. I've been going over some designs in my head,and I think I've figured something out, but you're right, Steve, the final version will have to be built and tested -- unless, I suppose, a computer program builds it virtually, but that requires certain skills I definitely lack, and software I don't own.

Actually, I'm thinking classic Cardboard Aided Design.

You would have to mock up the frame and the bonnet where the pivot takes place keeping in mind the nose needs to arc forward as it tilts.

Didn't Saab 900s have a similar hinge mechanism?

Some of the Buicks used the raise and tilt also. Might be easier to find in wrecking yards.

Mounted much higher than expected.

Great find Fictioneer! thumbs up I tried searching for more stuff by that guy to hopefully see how the front ended up; couldn't find anything related. I'd really like to see how it would look without the Overriders.

Determining the virtual pivot center is very similar to how suspension design determines roll centers.
It's no accident that the stock Spitfire pivot is located so far forward.
Anyone contemplating this kind of mod would do well to model the virtual pivot location, and mount
the hinge accordingly, rather than blindly following the tyranny of doing what 'looks right', ie level
and parallel to the ground.
