My plans for the '62 Sprite I'm doing will follow a couple steps. I plan to clamp (maybe even bolt) the major components together first to check fit and position for brackets. The Bugeye style brackets may work as is, or may require modification. The mock-up should help determine that.
If all appears doable I intend to weld together all the large components into a single unit, as is the Bugeye bonnet. I will likely use a stip of 3/32 or 1/8th steel between the hood (bonnet) and fenders to fill the gap and also add some strength. Once welded and ground flat very little filler should be needed. Gussets will be added at the bonnet rear top corners as on the Bugeye.
As my car will be bumperless, I'm hoping to get the tilt to work with a simple single pivot on each bracket. If there is a problem with clearance, then a more complex sliding pivot may be required (lift slightly, pull forward a couple inches, fully raise).
Should be a fun project!
