Can someone help me with detail on these? My F4 came back from the paint shop with the giraffe door detached and the hinges I have don't seem complete. I have the roof mounts with an open 'slot' (female) for the door pins (male) but nothing to secure the pins to the roof hinges. The door mounted pins also seem too long, as if there is a part missing that fits between the door hinges and the roof hinges????
