Just a thought when I pondered this. Do the earth points need to be positively locked? I.e a bolt and a Nylock to show that it is secure. I remember Ash had a problem with his brake Tee being rivnutted on and he had to replace with a bolt and Nylock. Would the same be considered with the electrics. Just in case - I was going to do the front and rear lights with rivnuts, but the main battery to chassis to engine strap with a bolt.
