well I do not know as I bought them at least 5 years before I bought the barracuda so something like 9 or 10 years ago and it was in a public auction.
I will check as I still have the cardboard but I do not recall of something writtten on it.
as for the brackets, I modifiy stock brackets to accept the new seats. I welded small pieces of metal because of the difference of width. it looked to be really solid and do not flex with me seated in.
thanks for your feedback.
Going to work on the front suspension
