Z Car Common Questions
Please note: this information is specific to vehicles produced for the North American market.
260Z owners: How can I tell if I have an early or late 260Z?
If your car was manufactured through August of 1974, it is considered an early 260Z. If it was manufactured between September and December of 1974, it is considered a late 260Z. Another way that you can tell the difference is that the early 260Z has the skinny chrome bumpers, similar to the 240Z. The late 260Z has the shorter, thicker bumper, with the black rubber ends just like the 1975-76 280Z.
What do you mean by Coupe or 2+2?
Coupe models do not have a backseat. 2+2 models have a backseat. 2+2 models were only made starting in 1974 (240Z’s were only made as coupes).
What years were specific models manufactured?
For US cars, the following models were made in these years (non US cars are different): 240Z – 1969-1973, 260Z – 1974, 280Z – 1975-1978, 280ZX – 1979-1983, 300ZX – 1984-1989 (Z31 model) & 1990-96 (Z32 model), 350Z - 2003-2009 & 370Z - starting 2009.
Where can I find the month that my car was manufactured?
The month and year of manufacture is found on the plate inside the door jam on the driver side.
What is a casting number and where can I find it?
Casting numbers are model numbers of parts that are cast right into the part itself. They are commonly found on parts like exhaust manifolds, intake manifolds, etc… Generally, they are a 3 digit code.
Which side of the car is “Left” and which is “Right”?
Left refers to the drivers side and right refers to the passenger side on US left-hand drive Z cars.
280ZX owners: How can I tell if I have a Standard model or a GL model?
The easiest way to tell is by the cruise control. While many 280ZX’s were built with cruise control, the GL model will have access to the cruise control on both the dash and on the headlight/wiper/turn signal switch. Standard models only have cruise control on the dash.
280ZX owners: How can I tell if I have Standard Climate Control or Auto Climate Control?
280ZX’s with Auto Climate Control should say “Auto Climate Control” right on the front of the Heater Control Mechanism. Also, cars with Auto Climate Control have a sensor that sits by the windshield on the top of the dashboard, between the clock and the glove box.
When ordering carpet, what is the difference between sectional carpet & sewn-molded carpet?
When the early Z cars were manufactured, they all had sectional carpet. This basically means that the flat carpet was cut to fit the contours of the cabin. To make installation easier, Z Car Source also offers sewn-molded carpet. This means that the flat carpet is cut to fit the contours of the cabin, and then sewn along those contours. This allows for an easier installation on the cars manufactured after 1974. Because of the layout of the cabin carpet, Z Car Source recommends sectional carpet kits for the 240Z's and 260's and sewn-molded kits for anything past 1974.
1977 280Z owners: When ordering carpet, how can I tell if I have an early 1977 or a late 1977?
Look at the rear edge of the rear deck carpet. If the side edges curve in near the taillights, then you have an early 1977. If the side edges come to more of a right angle, then you have a late 1977.
