Had a really good look at this on the weekend, and as far as i acn see it's not the rods that are the problem, but the actual metal leaver on the door lock, i must have bent it

I tried bending it but it is still intermitant, it gets stuck sometimes!
Anyone got a spare drivers lock/catch? (i am not sure what this is called)!
Also it has the plastic arm atached to it which is connected to the two rods, how can i remove this plastic bit, or is it part of the catch?
