Just a couple more pictures here to show the shape difference. Although you could probably bolt the on, im not sure how the fitment would look like since they are shaped differently. Another note here is that the 04 tsx did not have heated mirrors while the 05's do but that is stateside so im sure about the canadian version. What im curious about is if the mirror part will bolt on to the base of the rsx mirrors. i might have to try that and see if it works out.
