Well in all honesty, If you don't have the required plastic rivet tool they sell on harbor frieght.com for $15 + shipping then its a PITA. The plastic rivets that the diffuser includes require that tool. You CAN do it without the tool but as mentioned its a PITA, I used a set of pliers instead. If I had to do it all over again I would just buy the plastic push pins they sell at pretty much any auto parts store which have been reported done here by some members and it's holding up just fine. You also have to open 10 holes with a 1/4 drill bit for the plastic rivets or aftermarket plastic push pins to insert to.Very nice, very clean R/T. How easy was the install?
I ordered from the dealership but in my case I knew someone who worked there that got it for me for $105.00.looks great i want to get one soon...did you have to order straight thru the dealership?
