I hear ya Karl. That's the way they always used to tell me and one shop still does but a lot nowadays have work sheets they want you to fill out. I guess their just trying to cover their butt's cause so many guys can't read a tape measure and add numbers. A buddy of mine is like that. The shop he was using told him to measure it and he didn't know how so he asked me and I told him. He gets one made and it's way too long and was mad at the shop saying they screwed up. I went down and measured and don't know how he came up with what he did but it was over 2" too long. Of course it was the shops fault and all the shop had was word of mouth so they ended up eating a driveshaft.
