Watch one, do one ,teach one. If I could just watch an exhaust manifold being drilled and tapped I would feel much more comfortable. I never would have bought the TST plate if they didn't send a video. Although I would like to know how long he worked on that break off screw before the camera was on. Heck, I had more trouble with the REAL screw at the back than he had with the break off screw. I was just about ready to give up after I mangled the heck out of it when suddenly it broke free.
