8.75 Sure Grip Spline Alignment Help

I know this question has been posted before, but didn't see a response.

Rebuilt my 742 (Clutch Style) sure grip and aligned both sets of splines. After running the car, pulled axles and now the splines seem to be misaligned. Can't get the axles into the second set of splines.

Is there a way to realign without tearing the entire third member apart again?
