Buddy it's not like I am going install a meter from some corolla...bolt to bolt 100% fitment is guaranteed with the cs5a/w, cs1a, cs3a meter hell even the ralliart or sport lancer(uk) meter can be fitted bolt to bolt...it's as original as they come. Some JDM lancers even have them so I don't really feel I am killing any originality of the car, because even when I sell it it will be a plus not a minus, for me in day to day driving i'd love to see what's going on thus thinking about it.
