Locking tab for GM module and others - hard to find?

[lockeed]

Hey Guys, I had to replace my GM module over the winter and while removing it, I damaged one of the locking tabs (blue arrow). I stole one tab from the module just below the GM module in the socket (don't know which one it is) to make sure I had good contacts and now everything works well with the door/windows... But my cluster stopped working (was woking fine before). I think this might be due to the missing locking tab on the other module...Even though the plug seems to be fully inserted.

Let me know what you guys think and if this locking tab is available somewhere!
