Can you show how big holes, etc how everything looks like below the floor mat? Good idea with 19 floor mats. I wonder if LX floor mat would fit LC.
Sure; I'll take pictures when I get home tonight.
Basically - the four seat latch points remain in the middle (obviously) and you will have three palm-sized or smaller holes on either side where the seats mount; I intend to fill these with some foam and carpet remnants. Lastly you will have the bolt from the vertical seat mount stick out from the fender well. It looks fine, but there is a small risk that this could scratch luggage. My plan is to mount a set of luggage tie-downs to the vertical seat mounts and then cover the bolt head with a rubber cap.
I can confirm that the LX mat is a perfect fit for the LC, provided you can stomach the prominent LEXUS branding! Pics to come.
