I'm referring to the 2 center hinges which for me they snapped twice in the last year (don't leave anything in the trunk and forget about it) but with some Gorilla Glue Blue Top with Blue Label, sandpaper, and 2 clamps and voila, fixed it twice, and its working like a charm.
As for yours the center panel, maybe a long metal thin bar, screw it on and
start again, haven't had that problem yet. Also I've sourced some of the air suspension clips from the UK to replace Cclips I'm currently using the for the wings. Love the car, wish yes I could get parts even finding a wreaker, but no luck as of yet.
