We ordered three billet couplers from Riva a few weeks back and when we went to put one on the Blaster we noticed that we had two mid shaft sides in one package. I called Pete at Riva and he gave me a contact number and the person to talk to at UMI. Not only are overnighting a new set with a call tag in the box to send the others back, they are paying for all the shipping. Its nice to know that there are some reputable companies still out there. :arms: :arms: :arms: :arms: :arms: :arms: :arms: :arms: :arms: :arms:
