I found what the issue is. When I replaced my steering box I had to replace the intermediate shaft also. But instead of buying a new one I put a used one off ebay
I know I know bad move. I see the play is in the slip yoke area in the engine bay where the two shafts slide into each other. I tapped the end of a wooden shim in there and the play went away. So I ordered a new shaft and hopefully this will cure it.
