Bolted the first latch onto my door to try it out properly. I will bond the post part in place on the door in the production version. You would only use bolts if it was a retrofit.
This is the normal position it would be in with the shock cord pulling closed. To open or close the door you would pull on the cord attached to the bottom of the latch so the bottom of the "L" shaped part can clear the back edge of the front section. When closing the door you have no choice but to latch it as the door sits up on the front section sticking up 11 cm from its closed position. To see the road properly with the door in this position is impossible.
