1/2 a degree is irrelevant, yes. I dont want to put faith in statistics, I want definates. My point was, your faith in automotive parts and the manufacturing techniques used are IMO, misplaced. The technology does exist to make good parts. Some companies even use it. But, low bidder, or off shore factories running worn out used equipment, or a labor force that is considered expendable, are where the majority of the parts we install come from. As I said, it's more to make sure things are right. I've found errors I've made when degreeing, thigns that may have caused running issues when it was back together. I've also found many parts not produced the way they were supposed to. Once installed properly, eveything is fine. So, for under $100, and an afternoon watching a video, a hobbyist can do the same quality job many shops charge over $100 for. Why not do it the best you can? Not leave the quality of the install at the mercy of economics.

Oh, BTW , the name's "moper"..as in head down pessemist..lol can you tell?
