I'm not sure but Frank had a lengthy conversation with Paul B, who is the director of business development for ANSA and he said that the ones he had were the last few available in the US and our actually old inventory.
He also said these were made for the Corvette but as a universal size could adapt to other makes and models.
These retailed originally for around $350 but these last ones are being sold at cost

$201.53 + shipping (+ sales tax for residents of CA or GA)
