The listing is for one (1) un-cut key blank that you choose from the list.
Choose the letter that's stamped on your original GM key. Aftermarket keys probably won't be stamped with a letter.
1967 & 1968 used the letter keyways also, but these blanks may not work on your model. The grooves on the key need to be longer to slide into the ignition.
Most 1969-1985 GM models, the key was stamped with a letter. It may fit other GM years. Some 1966 models didn't use the letter keys. They only had the key code stamped on the knockout. They use different key blanks.
The letter on your key is not your keycode. The letter determines which blank you need. I have highlighted in red where to find the letter on your key.
Before you have the key cut, slide the uncut key blank into the keyhole. If the key doesn't slide in, it's the wrong blank.
You will have to take the blank key and your current working key to a locksmith, hardware store, or a reputable key cutter and have it cut before you can use it in your ignition or lock.
