Help with hood
I'm not firmiliar with the GTO wiper assembly nor the washer fluid, but you could maybe try extending the hose (guessing it's a rubber hose?) from where it would be on the hood and attaching the actual spray nozzle onto the wiper arm, using either 5 minute epoxy, jb-weld, or something like that. I would think the problem though would then be pressure. Since you've extended it, the same pressure might not come out as much because it's over a longer hose, but it still might be too much, maybe slightly kinking it would help bring the pressure down. Not sure, though, just an idea.
