Hi, I am looking at swapping out my tailights on my 65 fastback for the long shelby/cougar/t-bird looking tailights. What year should I be looking for and what all is needed (bezel, lens, housing, gaskets). I have seen some for a 67 but I thought the 67 mustang (don't know about the cougar) had a concave tailight panel so I don't know how that works on the flat 65 tailight panel. I realize that I will need to cut the tailight panel, so that is really not a problem. I saw a right up tht used 3 65 tailight housing each side and the t-bird bezel. I would eventually like to go with the sequential lights but for now just the tailights. What have other done. thanks
