floor mat

[Nick 66]

I was wondering what is the best floor mat for my '66 f-100? Cause I ordered one from Dennis Carpenter, and I am not satisfy with it because it doesn't fit well, and only goes to the back of the floor pan. Is there a mat that is thicker, and that goes back to the gas tank? thanks

factory style mats only go to the back of the floor pan.
what if anything did you use between the floor and the mat, as this does affect how it lays down
