There are two different parts books for the TC, one for the early and one for the late model. I think you have the "early" model. I believe the early models had the chrome rear bumper and the quarter turn hood latches. I believe the "late" models had the painted rear bumper and I think they had rubber rear hood hold downs although the late parts book does not show them. The windshield was designed to be folded down to make a low profile for loading into a station wagon or whatever. Someone else can correct me but I think that the early models were painted 73-74 blue and the late models were painted 75-81 midnight blue. One other thing, both parts books say 1975 but the early book has the same cover page artwork as the 1974 parts books and the late parts book has the same cover page artwork as the 1975 parts books.
