I was talking to my dealer today about the tail locks for Walkers. I asked him if they were easy to put on...he said they take 6 hours of labor if you go through them to have it put on. I couldn't believe it...i can put a new motor in my truck in that time! The guy i was speaking to was a salesman...so im not sure how good his word is. Does anyone have any experience with the installation of these tail locks???...does 6 hours sound right?
