Hi,
I´m wondering if NASCARs from the 70´s used metal braided lines (fuel, oil etc.)?
I found these pictures; http://www.hodgerestorations.com/Race%20Car%20Restoration.html
I realize it´s a restoration i.e. it may not be 100% historical correct, but judging from this picture: http://www.hodgerestorations.com/current/14%20Race%20Car/100%2084.JPG it seems that at least some lines were plain rubber ones.
Any help is appreciated.
