Luke harness buckle swap
1. Carefully peel the label off the release latch
2. Remove the release latch by removing its retaining screw.
3. Remove the two screws that retain the plate that has now been exposed. (beware that this plate retains the harness locating peg return springs, and these springs are preloaded.)
4. The harness locating pegs are now exposed. Note that the fixed strap is located with a plain sided peg, and the removable straps are located by pegs with a fixed washer.
Swap the plain sided peg into the position you require for the fixed strap.
5. Refit the retaining plate, taking care to locate the springs in the cut outs in the retaining plate.
6. Refit the release latch.
7. Refix the label to the release latch ( I've used double sided tape to refix the label)
