Restoring a 67 coupe, 289, C4, non-AC, manual drum brakes and manual steering. Will upgrade to power front disc brakes and power steering during the restoration. When I removed the fuel lines prior to the car going to the body shop, I failed to pay attention to them. Were they 1 piece or 2 piece, 5/16 or 3/8? The car was built 5-11-67 in NJ. Just curious if there is a way to figure out if they were 5/16 or 3/8, 1 piece or 2 piece.
