while backing into my garage i broke the plastic around the passenger side mirror. the cover behind the mirror did not break, except for some little clips on the inside. the part that broke is the plastic edge that you see that is around the mirror when looking at the mirror. has anyone ever changed this part? do you have to buy the whole mirror or can you just buy the piece and if so, how much was it? also how much does cover behind the mirror cost? a response would be greatly appreciated thanks in advance
