Nitrous plumbing A1A...??..

I got the nitrous plates today and sure enough Summit had given me the wrong AN size.. :BangHead:... so all the fittings and everything that I ordered are all the wrong size and are going to get sent back tomorrow. I called and asked what size they are and they said they'll have somebody pull a box and call me back tomorrow which was a week ago. They said 4 AN.. I noticed one box had been opened and inside the Box the ends of the hoses were cut out of the vacuum sealed and taped back in. It was obviously the box that they had opened up to verify. And also obviously they just took a guess at it and didn't fit a actual fitting over it or take a measurement...
I basically called them and told them they shot themselves in the foot...
