how much slip yoke play

Does anybody know how much play there should be on the slip yoke or tailshaft side to side movement on a A-833 transmission. I have a major wobble in the driveshaft i can wiggle the tailshaft in the transmission probably 2 0r 3 mm. seems to much . the transmission was just rebuilt with new bearings and synchros. maybe a snap ring has failed.Can anybody try and wiggle the drive shaft on there ride and see if they get any play at the yoke.

thanks all
