The hood of my car is a lightweight fiberglass race (rough) part that is held on with four latches. When you want access to the engine bay you just lift it off. Now I live in a notoriously windy city, and this thing would be gone if you just removed it and put it down anywhere! So I decided I'd add two pins to the roof, and a hook at the front, so you can latch the hood down securely. Works great! I haven't done the front hook part yet, but when that's done you could drive around with the hood on the roof. Perfect for Beach Hop!
Here's the inside of the roof, showing the plate and captive nut system I'm using to mount the pins. I'll clean and paint this bit up, but it's all covered with the headliner.
This is the in progress mold of my modified bumper. I added the alloy brace to keep the mold rigid.
And here's the fiberglass bumper I made from the finished mold behind it. Not much good for bumping, but it only weighs 1.3kg!
