Yes the output shaft of the tranny sticks out a bit.

making a couple of assumptions here (a dangerous thing to do I know)
you have installed the drive shaft on the spline and hooked the rear u-joint
to the rear end and the over all length appears ok, except the center
support mounting holes aren't lining up. Is it possible the bearing wasn't
pressed on far enough, or that it is the wrong bearing? Or it was pressed
on incorrectly and the retention ring kept the assy from pressing on far
enough?
Timken part number HB88107E

You say compared new to old, by eyeball or did you measure?
