I couldn't find this exactly posted, more like suggested. So here's my look on it!
Well, I was in the mood for a bit of experimenting. That, and I was tired of Salt and muck getting on my new carpets. At walmart, I spotted these All weather "utility mats" on the bottom shelf near the regular mats. at $8 a piece, I was willing to try it out. If they didn't work, I could easily take them back.
As soon as I got into the parking lot, I threw one into the passenger floor. Perfect fit! The drivers side.. needed modifying. Got home, cut a couple inches off one end, stuffed it in the grove in the bar under the seat. Worked perfectly. Looks about like they were made for it.
I'll work on pictures if you want them...
