S6 Projector lens replacement question

Hello,

I purchased some replacement projector lens for my '07 S6 but I can’t figure out how to remove the projectors from the headlight housings so I can get to the lens.

With the headlight removed and the ballasts removed I see 1, maybe 2, screws that seem impossible to get to but I’m not even sure they are what is holding the projector in.

Here is a picture of mine opened. If anybody could point me in the right direction I would really appreciate it!
