Yes, I did do a write up a few years back when I fabbed it all up. I was just going through my picture library and for some reason I am missing a few pics from the build up, go figure.
I honestly don't know what vehicle the donor cupholders came from, I got them from a broken console they had laying around, it looked to be about the right size and the price was cheap.
You can buy Fiberglass in just about any parts store, you also need to buy fiberglass mat which is a tight weave cloth, it gives strength to what you are fabbing.
