Sharon at Sharon's Web did mine for my Barracuda. She made them from parts she had in stock because the ones in my Cuda were not originals. Excellent work and definitely recommended

I used Ssnake Oyl to restore the ones for my Superbird. Restoration quality was very good, prices are somewhat high, however the shoulder belts were made too short and had to be sent back.
