Loosen the thrust bearing cap, SMACK the crankshaft to the rear with a bigass deadblow or other cushioned hammer.
Then SMACK the crankshaft forward, torque the cap, see what the end-clearance is.
If half of the thrust main is slid forward, and half of the thrust main is slid rearward, there may be little or no clearance overall. When both pieces are slid forward, you'd likely have proper clearance, AND the thrust bearing is in the better position for accepting clutch or torque-converter thrust.
If that doesn't work, remove the thrust cap entirely, re-check end-play. I had an Oldsmobile with too-little end play, the machinist that cut the caps before the align hone got one tilted. The cap-side bearing wasn't square to the crank.
