I got the filter installed today. I made the cutout yesterday; it was pretty easy. I scored a few times with my sheetrock knife and finally cut all the way through. Then I looked at the instructions and realized that the filter needed to be bent as it went in since there's not enough clearance below. I also realized my wheel tubs at the firewall were in the way to bend it like they showed and figured it wasn't going to work, but then I turned the opposite direction and bent it towards the driver side. Aha. Success. (The fan assembly is even modified on mine to fit with the tubs there.) One note- the instructions show leaving the driver side screw in the cover assemble being left in place and just shoving the cover out of the way. Mine was missing that screw so the cover came all the way off and it was a ***** to get those screws lined up and that driver side one (I found a replacement) was extremely hard to install. Many cuss words were muttered. If yours has that screw, leave it in and then it's easier to locate the other holes since the left-to-right is already set.
