47-55.1 Windshield wash nozzle location for AD?

[leegreen]

I want to add washer sprayers / nozzles to my AD.

Does anyone have pictures of the nozzle they used, where you located it and a report how well it worked?

I did find these threads:
this one seems to show factory option nozzles for an AD, but not in location. I'd really like to see where the factory put them.

This one shows a couple options people did. I don't have a lathe and am not too fond of the hose to wiper arm look although I am sure that will work well

I fear drilling holes and ending up with the aim wrong!
Some newer plastic nozzles have the hole in an aim-able ball, but I have not spotted one designed for hood mount that had the feature.
