Hood hinges,, Crown Automotive RT34095 fit the drill pattern on the Roxor. (The bolts that come with the hinges will not fit the Roxor threads).
M8-1.25 x 20mm bolts will fit the threads in the Roxor.
I built my half doors from left over 1/8 aluminum (from my roof project).
- traced the door onto cardboard, and then to aluminum.
- used a circular saw with an aluminum blade for straight cuts and jig saw for each radius.
- belt sander to perfectly match each radius to the body
- powder coated doors in wrinkle black
- door latches from eBay
I got fancy with bends and bevels along the top edge. To make bends, I cut the aluminum to half its thickness, made the bend, and brazed the the fold (since I don't have an aluminum welder).
