Note that the squirter hoses only go through the firewall for 1970. They do not go through the firewall in 71/72 as the nozzle is mounted in a different location on the hood. Most of those other items are easily changed for not a lot of money. As far as if it is a real SS is the biggest issue for sure. Has some components that certainly suggest it could be an SS (rear bumper, SS rear trim, shock protectors, dash knob with symbol). I have not seen anything that suggests it is not an SS so it would need more investigating for me to buy it.
