Replacing the spider badges

[81spider]

I've bought new badges for my spider, but I can't figure out how to instal.
Does any one have any help to share with me?
Thanks,
Rob

Do they ahve adhesive badges or slots to fit in (little bits that locate in holes that stick out of the back?)

They fit into slots. I can't seem to get to the underneath of the badges, and I'm affraid to just pop them out.
