how to connect plastic shower drain to 2" copper drain line?

[showerpain]

I am having trouble locating something that will allow me to connect my new plastic shower base drain to my 2" copper drain line. I am replacing an old shower and can not find any flexible couplers for this situation. Please help me before I go crazy!!!

Any help would be appreciated!

Thank you and I HOPE this works as I've looked at many items and nothing seems right. Every plumbing store I go to says they don't have what I need so hopefully this will do it!!!!

Thanks again.
