Source for rubber bed mat?

[cacauba]

I made one for my nissan a while ago out of a cattle mat? i got it at a farm and ranch supply place and they come in two different sizes and thickness. i got one that was 4X6 and 3/4" thick for $40 i think. the other one was 5X7 and 1/2" thick if i remember right. that one was $60. again if memory serves me correctly. i will tell you that NOTHING moves once it's in. at the time they wanted $100 for a custom fit one that was very thin from the auto supply places.
