Inside pipe grabber for 2" PVC

[rustyadams_99]

I am installing a Tile Ready shower base with an attached drain that will adapt to a 2" PVC pipe I have installed. I have tried setting the base over the pipe and it is a little snug so I would like to be able to pull the pipe into the drain fitting from above but am not sure if there is a tool designed to do this or not.
There is no access to the drain from below so it needs to happen above. Any suggestions are welcome.

If the connection to the shower base requires a rubber doughnut, the trap will need to be supported for it to be driven into place.

Thanks John....I do not believe there is any rubber donut based on the plans that came with the base.

Good idea Frodo...have you used this method before?
