Or, what gauge should it be if it is 6 feet long or there abouts. Was the stock gauge 1 gauge? 2 gauge? What should I use? The 68 - 70 Rivs have the battery on the driver's side, so the cable is quite long.
battery cables i believe the battery cables , (side mounted) for my gs 350 are 4 guage wire . i would use 2 guage as i believe that your car is a 455 (correct ?)
