The saga continues. I ordered a new OEM pilot bearing...same result as the original...it does not fit. I don't see or feel and burrs or deformities on the input shaft and lightly sanded (by hand) it to ensure it was perfectly smooth. I also picked up a universal clutch alignment set. The bearing adapter one size smaller (a tiny fraction of a mm) than my input shaft fits perfectly through the pilot bearing. Pics below for more detail.

Dry fit of pilot bearing to input shaft...I suspect a different input shaft as both the original and new Ford OEM bearing do not fit...bearing size has been cross referenced directly from online Ford parts sites.

Input shaft diameter measurement...0.595 inches...equates to 15.113 mm...caliper has margin of error of .003 mm. The inner diameter of the bearing is ~0.586 in...14.884 mm. There's a reason it doesn't fit. But it should be the original shaft as I sourced all my own parts and kept all the old parts. What am I missing?

Brand new pilot bearing.

Universal clutch alignment tool set.

Now how do I figure out what pilot bearing will fit?
