before I pulled the motor, I felt a little play in the driveline when I reached into the bell housing and pulling on the driveline......
AFTER I pulled the motor I grabbed the pump shaft and move it...... nothing. Solid .with zero play in it......I'm wondering what would do that .....it's the old style Rockwell driveline. The I joints seem solid..... it was bolted tight to the flex plate .....the pump shaft looks good..... spins freely . the splines look ok as well as the shaft on the driveline itself

and ideas?

A bit of slop between the splines on the shaft and the coupler is normal .  Look at the splines on the shaft to see if they're starting to twist.  Normally if you have issues here it will be hard to get the coupler to slide with out binding.  Spread some grease on the shaft and reinstall it.  This will help tighten it up and quiet it down from clunking.  ( I'm feeling a bit uncomfortable now) It's probably fine.
