As Charley suggested, in the past I've tweeked the bracket to get the door to close the last 1/4 inch.Before I took the car apart to paint it both doors shut perfectly. I hate to tweak an original part to make the door fit....at this point anyway. But may end up doing just that.
have you tried loosening all the relevant fasteners.. making sure it opens/closes easily, then carefully snugging them back ??
