Just want to update you guys on what I've done to my car since I've purchased it. Pictures are down below. Feel free to ask me any questions regarding the installation/purchase of the grill and the quad diffuser. All of these items are after-market and can be purchased on eBay. Also, "Yay" or "Nay" on the 4matic debadging? My dad hates it but I kinda like it.
As for making sure they align properly, there's a hidden insert for these tips within the plastic. People mistake it with the 2 identical slots that match with the tip hangers but it's actually above it. I also got someone to hold it for me from the outside while I tightened the bolts underneath.
