yes they are scarce for sure, but keep looking, they do show up
seems like something must have happened with the check arm to just affect that corner - those arms do get worn so they flop about into bad positions ... that crease looks like where the stress 'ended' when the damage happened, the skin had to wrinkle someplace ... I've looked at the pic a number of times, thinking how an 'opposite' force might be applied - a port-a-power is the best way to ease things back in shape without causing more damage in another place, if you can come close to an exact opposite force to what caused the damage, but you might have to do it with the door in place, brakes on, port-a-power against the garage wall!
good luck with it, if I think of anything else I'll post it here, or if I hear of any doors around
