I'll second that! I think the bend must also be important... If it is in the wrong place the door doesnt close. Mine is a bit nasty and ended up with a slot in the sill. I lost one of the bars and made a replacement from a 9 inch nail. I won't offer a photo... It is functional but a bit of a bodge.
Here are the pictures from my car, the design of these is pretty rubbish, I spent a lot of time fettling these to get them to work properly, the hole in the sill had to be elongated and as Nick said the bend in the rod is crucial, get it round the wrong way and the door will not close. The rod must not bind against the hole in any way over its travel otherwise again, the door will not close properly.
The whole arrangement of the off-set alignment of the door hinges and the door restraining rod is so badly designed I do wonder what on earth they were thinking of!

You have reminded me to take a picture as well Gary.
I think part of the issue with the rod on your passenger door is that it is not sitting straight, it angles down quite steeply from the bracket. If you open the hole upwards to allow the rod to enter at right angles to the upright you will almost certainly find it shuts without any issues.
