Tubular upper arms-I feel lucky tonight

I just got a new disc break conversion kit yesterday from a company and when I opened it up to my horror were a set of Cap tubular UCA's.They were supposed to be the stamped UCA's like the OEM ones. When I called the company they said the correct ones were on back order and they were substituting these. I told them I didnt want them and they promptly gave me a UPS return authorization number to ship them back and they are going to give me my money back for the Cap product. How ironic, I have been following this story all week and chose to go with the stamped UCA's because of it, and when I finally get my breaks I was mortified to find these frigin things instead. Now I need to decide what I want to do for UCA's.
