Hope you don't mind my comment, but I went through this with WeatherTech...
I just want to help.
They are very good floor mats.
They make these to fit different configurations of the same vehicle.
Front mats are molded to fit over carpet, or over vinyl (WT). Also front mats for crew cab are different from extended cab. why? IDK. maybe it the placement of the seat rails is different. The anchor button locations are different.
You (buyer) really must look up the mat product number and make sure you have the right vehicle for it.
