The side of my garage jumped out at me and crushed my driver side mirror. The housing cracked, but the mirror glass, electrical components and reflectors survived.

I need to take the mirror and electrical out of the damaged housing and transfer the new housing I bought from a dealer. However, the clips aren't very forgiving and I can't seem to pry them loose without fear of breaking something vital.

Any tips on how to make this happen? I accidentally broke one of the clips on the existing housing, so I guess I could go that route, but I'd rather not out of fear of breaking my mirror or something electrical.
