Hi Tim
I will check with the classic people in the morning to make sure it is what they advertise. I have been looking at those slits in the mats for over a year and have been thinking of changing it out. Doing a little work on the truck during the non driving season and decided to do it now. That Unison seat is one of the coolest options for these AD trucks. You will enjoy it as much as I do. Thanks again for the info on the mats. Nice to hear from you.
Best Regards
Walter
