Ionix is the bottom of your parcel shelf aluminium too?
I was going to remake one for the Capri many years ago.
The one I found was the std fibreboard/cardboard thing from whatever they used to make them out of.
Someone mentioned to me at the time about safety having what effectively could be an aluminium blade just around knee height in the case of an accident. I hadn't though of it at the time.
It was remade out of cardboard and I reused the time edge facing.
Not trying to pee on your parade at all, as you've just done a great job.
Just something to consider maybe.
