68 Barracuda Rocker pinch weld pics

Im restoring a 68 Barracuda. A friend of mine asked if the pinch weld along the bottom and underneath the rockers are blacked out from the factory. I believe on the later models (70's) they are but not on the earlier models (67-69.) Does any one now for sure? Does anyone have a original paint car and have proof? Any pics would be extremely appreciated. Thanks in advance.
