If you bored a hole in a plug for a .0001 clearance for the spline end and then turned a true spud on a lathe and slid this on to center drill your truing plug and put it on the spline end you could check the crank between centers.
Thought this was on the newer cranks 07 and up. I will not more when I split the cases on a 04 I am working on. Just for ***** and giggles I am going to see what my truing stand says. I have all ready checked the end of the pinion shaft where it goes into the cam plate and it is REAL good so if it shows way off then I will know.
How do the crank people say then can true them with out disassembling them? That is what Dark Horse says and they are the ONLY ones other them I in the future to do any of my or customers crank work.
