painting side mirrors?

Does anyone know how to take them apart? Do you just have to tape off the mirror and try to get in the cracks/edges or does it come out somehow? Im painting them up tomarrow just not shur how to get inbetween mirror. Ill probly fig it out just looked at it and didn’t see any screws or tabs to pop it off and dont want to break them.

According to the Helms, there should be a hole in the bottom with a screw visible inside. Unscrew that and flop the mirror out.

there are 3 screws on the base plate then you have 1 screw under the mirror ( youll see it by the base plate ) then you have screws on the inside
