I agree the pictures are a little hard to tell, but the pictures of the front wheels look like a lock ring to me, not RH5

I won't argue at all with crenwelge as to them fitting as I have no idea, assuming these located close enough I would go take a look at them in person to confirm if they are or are not RH5 as you now know they will bolt on.
