As you can see I have found a screw but it may be a bit short. Previously I couldn't fully tighten the screw or the door didn't lock/unlock! It seems I have a mismatch of parts!

It appears to be muc4146 possibly from a 90. But my doors have push button handles!

1993 defender with the lock barrel held in by a screw. I am guessing it is a 6 ba screw but I would like the correct answer

My door lock has a screw to hold the barrel in place. The screw has fallen out and needs replaced. What size is it?
