I have the PS Louver. It's made from aluminum so it won't rust. I got the powdercoated one. Here's some notes that may help you.
To cut the hood you want an electrical 4.5" angle grinder with a cut off wheel. You can get one at harbor freight for $25. I got a Dremel 10 amp one at lowes for $80. The cut off wheels are about $2. I only need one cut off wheel. It's more like grinding than cutting. It takes a few strokes to get through. I tried a 3" harbor freight air cut off tool first and it was way too weak. One guy used a dremmel, but that is ridiculous. I guess that took 6-8 hours vs 2 hours with an angle grinder. If you have like a 100 gal air compressor then an air angle grinder would let you vary the speed. I would just get the electric
Here I a video of me cutting the hood.
I would get a full face shield and some gloves. Long sleeves are a good idea too.
Your also going to need a 3/4" and 1" hole saw. That's about $20. The pilot drill is attached with an Allen key. You may need to pick up one of those. Of course you will need a drill.
There is some glue that you will cut. It burns and has a super nasty toxic smell. It will give you a headache. I would also get a charcoal painters/surgeon mask. That's about $5.
You'll also need a punch for starting the holes.
You'll want to get some touch up paint. I also sanded down a bit the bracing underneath and sprayed it black. Be careful by the hoods spray nossel hole to tape that off. I would pick up a roll of 2" painters tape. That should allow you to tape off everything that's not getting cut.
You will defiantly want 2 sharpie markers. They will perfectly hold the template in place where the hoods nipples are removed.
A magnet wand can come in handy after cutting holes with the hole saw.
Make sure you have a tool for the attachment bolts. I think it's some type of hex bolt.
I did the hood with it still installed. The angle grinder sparks ruined my windshield. I embedded metal filings into the glass. If I would have put a piece of cardboard covering it at the start I would have been good. You also need to cover the engine with this technique. I used a tarp and it now has tons of pin holes from the angle grinder sparks. I propped the hood open with a 2x4 laid over the radiator. Of course I used towels were the hood rested on the board. You have to remove the air vent to get the innermost bolts in. I would likely remove the hood if I did it again.
If you take the hood off be the top obvious bolts it will break a paint seal on the bolts and around the hinge. A better method is to take off the middle air vent, and removing the hood from the bottom attachment bolts. I was too dumb to realize that I could lay the hood gently on the windshield vs just propping it on the support rod. That would give enough room to put the grunt on the bolts needed to get them off. First you need to take off the wiper blades to get the vent off. You pull up the plastic at the very base of the blades to get to the nut. Then bend the blades up a give a good wiggle. You will also need to remove the 4 push pins in the center of the air vent. That was a bit hard. The outside bolts are T30.
When your cutting you want to be careful not to cut through the underneath structure. I would try to mark its general location before cutting the hood. Being that it's glued down it can be hard to tell when your through one layer. I ended up trimming the structure some. Some of the holes you drill that's a factor too.
I would move around when cutting the hood so no one part gets too hot. It's also not a bad idea to let your angle grinder cool down after about 20 minutes of cutting. Always give the grinder the respect it deserves. Keep a good two hand grip on it.
The project took me 12 hours. I'm sure I could do it in half that. I really went nuts with a small touch up paint brush on all the drill holes. I also went ape shit making sure the holes looked nice underneath and totally de-burred.
