No,Thanks thou I know what I have lol came off a ls 1 supercharged camaro that made 650 to the rear wheels just can't remember if they were 60's or 80's the ones in my signature came from full throttle.
these are solid black no rings hard to tell the difference between the 60's and 80's going to take them outside in better light and look at them with a magnifying glass maybe I can come up with some more numbers I think there 4-5 years old
