I'd just spend half a day looking around various body shops. Any body shop could cut a hole in your hood and weld in the new scoop.
I'd definitly put it in because I think the cooling for your engine is critical. Consider the fact that you don't have an intercooler.... you at least need a scoop to let cold air in. I doubt you'd kill your car just driving here and there, but NO HARD DRIVING. And mabye let your car idle and cool off a bit before you turn the engine off.
