Hi,
My 96 Lumina has a little spigot that has been broken off in the box
that separates the engine area from the washer 'tray' area. The
spigot connects the hose running from the washer reservoir on the
engine side to the hose on the tray side, leading up to the wipers.
Is this little part available separately, or is it a permanent part of
that little 'block' that installs into the firewall?

Thanks,
Louis
