@joeg One thing I do know .. and the good news for you buying parts, is that the front wiper arms come with the 2 sprayers attached. So the sprayers move with the wiper arms and spray just behind / in front of (?) the wiper blades as they swipe. There are two spray nozzles on each wiper arm, 1 partway up the arm, 1 further up the wiper arm. So I bet you would need a tubing extension pieces to connect them on the new wiper arm.

So I bet you'd only need for the front... something like

wiper arms x2
tubing pieces (I'd prob get genuine LR instead of parts store stuff / vac hose as that will degrade quickly in UV light.. btdt)
blades

Same thing on rear, but just one sprayer on that wiper arm.

 

Thanks!
