If your setting up for a fuel gun hole 'directly' above the tank lid, using a cable tie to pull open the tank, then sure like Robert had at the EC with long grub screw would be fine.
But it's just the a club/test body shell, where the bulk of my refueling is going to be from a bottle, pulling the tank open with a thumb, and I did not want the hole that far onto the roof for all that, the hole I made is about 8mm onto my roof, meaning 3rd post kind of needs to be further forward.
I don't see how what I did can foul the servo saver in any way?,
