So I need to drill through a 1992 body, unspoiled for all them years, to mount 2 reversing cameras at the top back corners of my tratter. I might put each bracket camera on the roof rack, or just under the rim of the roof. They're wired sony tvl 700's. I'm guessing it'll be an M8 or M10 hole. Where would you drill the holes? Cheers in advance if you reply.
