Priceless! These are remnants pieces I've kept https://pbase.com/9146gt/image/164402966 that were left over from when we trimmed the damaged https://pbase.com/9146gt/image/138986738 original mesh lath material used to 'to-off' my newly fabricated 914-6 GT engine bay lid https://pbase.com/9146gt/image/139404626. Here is proof https://pbase.com/9146gt/image/164402968 that the mesh lath expanded metal material the Porsche factory sourced to build the 914-6 GT engine bay lids was in fact Aluminum https://pbase.com/9146gt/image/164402976. After all, the goal was not only to provide added cooling to the 914-6 GT mid-engine location https://pbase.com/9146gt/image/144603022, but also make these race cars just a bit lighter.

Below are some close-up photos of the diamond-shaped pattern, and also the overall metric dimensions (I'll say close enough to try and source your own if available. BTW, good luck with that!).
