There shouldn't be any vertical/lateral/radial play between the coupling. If the correct halves were used, there is a pilot step on the face of one coupling half that fits into a counterbore on the other coupling half.

I know that once i bring the halves together there is a lip where the sit together. However it is before I slide the coupler forward that I am asking about. The coupler is well attached to the shaft. I am trying to know if there should be any play on the shaft at the coupler.

It's normal to be able to move the coupler end around a bit. The trick is like Pete said, to make a quick V-block for the shaft to sit in, and then go back and look at the shaft passing through the strut. Is it concentric? Is it high in the front and low in the back? Adjust as needed from there, and when you get it close, put the coupler on the pilot and check again!

My 80 Tique shaft strut's bore is such that the new strut bearings slide in by hand! The old ones slid out (well one slid out the other came out with a little driving with a piece of wood) after set screws removed. Seems like this is too loose. Opinion/expertise?

Mike,
They should not slide in and out by hand. Somethings wrong. Does it appear that the old cutlass bearing spun in the strut wearing the strut I.D.? Did you put a brass/rubber back in or one of the two piece plastics. I've never see one of the brass ones out of tolerance but there's always a first time!! The plastic bearings I have heard of tolerance issues. Better get the inside and outside micrometers out and do some measuring!

If the strut is over and not much more than about .010" over, I'd be inclined to install the new cutlass with Locktite Bearing retainer 638. It will fill spaces up to .015".
