Check if your Subaru has / needs a plastic tray
Size: 72880-FL00A
Works great for my 2015 Subaru Outback, not so much for my 2013 Impreza in terms of installation, missing plastic holder for 2013 Subaru Impreza, while 2015 outback does not require the plastic holder

Fits my 2026 civic sport perfect!
Size: AF151
No issues, fitment is perfect. Great quality for an excellent price. Dealer wanted like $24 for a basic one. Nah I'm good I'll just go on Amazon and get it for $8. Took 30 seconds from start to finish can't get any easier.
