Was going through and getting my door locks working, and both my door bars were broken. I googled some part numbers and didn’t come up with much, so I 3D printed these replacements out of ABS. Seem to work well. There genuinely might be a source for these but if anyone wants to print them here they are. Files will be in the next comment.

Make sure you’re printing them with a flat down and support material for strength.

 

cool printing does it leave space for the ball to pivot in?
If not a dremel with a small round grinder bit will open it up so the ball stays put.

Last I checked these Factory parts are readily available,
Roger has them
