Got one of these for the offside door, arrived in a 90 degree configuration i.e. holes in same orientation (door shut?). Forced into straight line (holes now 90 degrees opposed) at which point the strap fell out from between the rollers! There is an arc cut into the strap which looks as though it ought to form a stop against something when the door is open but I can't get my head around the correct configuration. Does the "hook" on the strap fit between the two rollers because if it does then the cutout seems redundant. I know the obvious thing to do would be to look at the fitted one but I'm waiting for a new door handle spring before I tackle the doorcard.
Thanks for any help available, a photo would be nice!
