67 barracuda formula s interior options

restoring a factory correct 67 Barracuda formula s 383 4 speed , the interior is different then any I've seen , the previous owner claims it is original but I'm not sure . they call it the Jan and Dean limited edition interior which includes high back bucket seats with vertical multi colored striping inserts front and rear. Has anyone seen this before and if so how can I validate the authenticity ? Much appreciated
