HELP! Capri Mk1 Bonnet Mounting Hardware

[Aether]

Final update:

I figured out what holds the main latch in: a large square nut that I removed when sandblasting the bonnet frame on the back side (pictured below). I think I was trying to be thorough. Ive now located the nut, sandblasted it and painted it with POR-15 for re-installation so the bonnet can be re-skinned.

As for the bumpstops I found some new replacement items on eBay that work really well (pictured below).

So now I have all the hardware to re-skin and reinstall the bonnet and get all the gaps right.

Thanks for your help peoples
