Measure the depth of the hole in the crankshft from the flywheel face and estimate where the input shaft transition to the spine is relative to the flywheel face and do the math.
Is it possible that the transmission input shaft got moved forward when you were working on the back end of the transmission? The picture of the shaft engaged into the bushing looks like it would be close if your mounting gap was eliminated. I do not recall what locates the input shaft but maybe a snap ring got out of place and the shaft moved forward and can not go back to its correct location.
