I wish I had better information for you about that shaft log. What a pickle! Mine lined up perfectly with everything in the factory positions once I had the strut straightened, new bearings installed and a new prop shaft and coupler. I've since had my engine out a couple of times and it drops right back into the same spot without need for any adjustment. Good luck and let us know what you figure out. Have you talked to Jason @ Viper about it, yet?
