Just documenting for Rugby and any others who may find it useful some pictures of the installed luggage rack.

Photos;










These three screws are all you use to hold it down on the ends. The fine thread screw (far right) is used on the rear-most hole in the trunk. It goes in to a metal stud which I will show a picture of below. The two coarse threads go straight in to/through the sheet-metal.




Rear-most hole has a stud installed.


Forward most hole (below) straight in to metal. Small gob of silicone around it.


Because some of the metal inside the trunk is double-walled, you can't see 90 percent of the screws driven through it. Instead you only see two, from the two outer - inside strips.





They are capped with rubber.



Rubber removed.



Last but not least, the best way I see for lining up all the strips is seen below
The center strip seems to be perfectly centered with the Subaru logo. Eye the rest out from there. The two outers that attach to the wing on the back as you can see attach pretty close to the edges of the trunk.



Hope these are helpful!

Very helpful! Thanks a bunch!
 

Was yours factory installed or did you drill the trunk and put the studs/screws in yourself?

It came either from the factory, or the dealer like that. I can't say which with any certainty. All I know is I'm the 2nd owner, and the guy before me didn't put it on lol

The question becomes where to get those screws and the caps... wonder if I should ask the soobie dealer or if I should try the hardware store

The screws look to be run of the mill coarse thread screws. I'd use self tapping screws if I were you. You would probably be able to get away with using self tapping screws everywhere, but that's up to you. You're in the north-west and these cars were real popular out there, I wouldn't be surprised if you find a dealer with a mounting kit.
