And that's what had failed on my drive.

Actually, I've found pressing on the upper part of the door to be much
kinder to the pins than pulling the door open from the bottom edge (think
about what the applied force reacts against). The trick, of course, is
not to let the clamp arm slam open, but to guide the door open gently and
let the arm rise slowly

:-(. I'm getting low on replacement doors too. I may have to start making
those hihgt parts from scratch.
Of course I've kept the parts I removed from this drive. If nothing else,
the door itself is fine, and the broken parts of the hinge may be useful
if I do have to fabricate one.
