That page is very helpful....

What I'm talking about is the offset from side to side of the centerlines of the rearend yoke and the crankshaft.... in other words if you drew a straight line throught the crank and to the back of the car...and drew a straight line from the yoke to the front of the car....do they need to totally line up with each other in the horizontal plane......

So the answer is "No"... they just need to be parallel to each other....like the "Vertical Views" A and B on that linked page

Which is what I have...so I should be good....
