Just search for 4Runner and download the pdf that has the install for their replacement mirrors - it outlines how to remove the stock mirror assembly.
Post some pics once your done, as I've been wanting to do this as well. Was considering replacing my SR5 stock mirrors with the heated signals, figured do everything at the same time.
Thanks.
