Help with shower drain

[neller840]

Hey everybody.. Well first post here. I have a house I bought built around 2002. The neo- angle shower was never finished. I'm trying to figure out the drain for it. It doesn't look typical from what I see for drain parts. Any ideas on what I need? Thanks for your time!
