I did more research on this over the weekend and found that these silly nozzles are very year specific.

For a '67 the part numbers for each nozzle are the same and they install like I mentioned for the Camaro above.

For '68 there is a RH and LH part number and there are 2 different part numbers listed for the LH one. One is 6 1/2 inches long and the other 2 1/2 X 2 1/2 whatever that means. I have no idea how these nozzles are installed.

My '69 Firebird assembly manual shows a completely different setup than the '67. The drivers side nozzle has a 90 degree bend in it, sits completely under the cowl grill and the hose for it goes through a hole in the firewall. Of course there are unique parts numbers for both the LH and RH for this year. Both nozzles shoot out from the raised center section of the cowl grill.

BTW, I was also blessed with a car with no nozzles, hoses or washer fluid bottle when I bought it, so I have no references besides the literature.
