126 door won't stay opened
 

hi ya'll
i'm having some trouble with both front doors. the doors won't stay opened. unless i'm parked with the bonnet about a foot lower than the boot, both doors will no stay opened. i'm assuming it has to do with the gizmo between the hinges. does anyone know first, what it's called. second, how to fix it and finally if i need parts, where's the best place to get them. thanks for your assistence. i'm disabled (right shoulder joint is missing) and everytime the door slams my shoulder, i see stars.
have a great thanksgiving.
