I didn't know they made an externder for it, how long is the bed with
that in place?
Its just the length of the bed plus the liftgate down. Its the same
style extender as nissans and other pickups have.
with re to the wind deflector, its a MUST. But you don't have to go
searching on ebay for one, 1stsubaruparts.com and all the other dealers
have them. Its a Subaru OEM part. I think mine cost $35 before ground
shipping from the mentioned site. But just get a quote from your dealer.
If its below $40 buy it from them because after shipping mine came to
around $43 i think.
Also, it takes two people to install it. It looks like an easy job and
it is, but one person has to force the deflector down against the roof
while the other tightens the screw with a #2 driver and wrench. Its also
a good idea to take your roof rack off if you have one. We have an
adapted Thule 2-bike rack on top of the OEM crossbars, but only put it
on when we're going biking. Otherwise it just creates wind noise.
