when the guy at the bodyshop installed it he made his own template out of cardboard. trim it lil by lil untill wrapped around the side marker. (2 halfs) after he got the shape he wanted he taped it together. thats our template.
as for refrence points i brought in a pic of a CTR sedan since it had sidemarkers and the fenders were similar. i noticed that it goes a lil higher than the lip on the fender. so as refrence points we used the middle of the head light (puttin tape and goin straight back) and the bump of the mirror cover above the fender (tape went straight down). we used the template placein it over the middle the cross points and mesured the points from the side of the fender and from the top and bottom so we can duplicate the other side. he made the cut after and then lil by lil opened the hole so the sidemarker snapped in.
ok i jus took a quick pic so u can try to understand what i used as refrence points i circled in red and red lines was where tape went straight. in one its curved cuz i took the shot at an angle so i can get close enough and u can see everythin. and in the other shot the blue lines was where he mesured so he can make the markers identical.
i hope this helps
several more questions- does anyone know what colors the turn signal and parking light wires are?all it is a plug that goes into the sidemarkers and wireson the other end, that has to be tapped into the ur turn signal. so its not plug and play will require u using a test light to find ur signal not hard to do even with out a test light
