When coupling up the drive shaft to transmission I installed the rubber seal ring onto the transmission shaft as it shows on the detail breakdown before installing the centering cross pitch circle, but when I do that, I'm sitting to far back from being able to reach the joint disc with the drive shaft. My question is, should I place the rubber ring/bushing inside the centering cross pitch then finish the install? Sorry forgot to add the detailed breakdown. Item 294 and 186 is what I'm referring to.
