Do I need to remove my old mirror housing to install this?

No—this glass swaps into your existing mirror housing. You'll need to carefully pry out the old lens and seat the new one in the same mounting points. Take your time with the removal so you don't damage the housing clips.

Will this lens fit inside my factory mirror casing without any gaps?

Yes, this is engineered to OE dimensions for your specific mirror assembly. Test-fit it before fully seating to make sure the clips engage evenly all the way around.

What if the glass doesn't seat properly on arrival?

Inspect the mounting tabs and clips on both the lens and your mirror housing for debris or bent plastic. Clean gently and try again. If tabs are cracked or clips are damaged, the housing may need replacement instead of just the glass.
