Well Daniel I hate to be the bearer of bad news, but you're actually not going to be able to use any of those Euro style ball mounts with your Curt Trailer Hitch Receiver # C11372. This is a class I hitch and the drawbar(s) you're looking at are for class II hitches which may have the same receiver openings, but they can not be used together - the ball mount will not fit all the way because there is a built in tab/stopper to prevent you from doing this.
It looks like all that's offered... view full answer...
