I though I read a thread here somewhere where one of the Posts said you could drill out the existing holes for oversized pins (I believe for a 123).
I believe in that thread I also ask how you know that the Crankshaft Dampener is lined up on the timing marks in referance to the pointer when you are finished.
Apparently afterwards you need to pull #1 Glow Plug, Injector an Pre-chamber so you can us a Dial Indicator with an extension down to the Piston Head and get the Piston at Top Dead Center and adjust the Pointer so it lines up with Top Dead Center on the Dampner (at Zero).
