n and all,=0AMal Mc Lures "lock" design is a simple two engaging blocks suc
h that the door is closed and the middle part of the door frame is pulled i
n, and over this step arrangement. They are no more than 20x20 x 6mm in siz
e, with a single rivet holding them in place, and maybe some redux undernea
th, knowing how Mal built. So you close the door, pull in at the middle bot
tom until it clicks, and then actuate closed. If something so simple needs
a mod, and how you would do any stress analysis, and of what, anything is a
mute point. I would say it would be impossible and based on a raft of othe
r suppositions. It's a simple addition, not a mod per se. =0ATR=0A=0A=0ASen
