Please help me

hi, now,I maintenance 1983 chevy EL CAMINO.
I want remove mirror of side mirror. remove mirror out of mirrorbody
could you please tell me how to remove mirror

The mirror is normally replaced as an assembly. If it’s just the glass you are replacing, it’s glued onto the platen. Get the new glass, then remove the old glass carefully (so you don’t get hurt), then glue the new glass onto the platen.

Why do you want to remove the mirror glass?

When my Sienna mirror got broken while parked in Puebla, a glass place near McAllen replaced the glass for $10.

thankyou so much!
