Have you got access to any big ass termites?

I'd expect that there is some sort of retaining clip arrangement within the body of each item, but that's a guess. If you disassemble each piece to a point where you can see behind the woodgrain parts, it might help. Alternatively, have a look at the Carbon Fibre parts that you are going to fit to see if they give you any ideas, it might be that these finishes are simply glued to the surface of the parts they are attached to.
