thanks, I am not sure if all the mats advertised are the same or if they are different manufacturers. Chevs of the 40's has one and so does Jim C. also Bowtie Bits. Looking for something that looks like it was formed for my truck, and not just a piece cut from a sheet.I do prefer ribbed look. My thoughts on the running boards are maybe there is a similiar shape and size for a car that would fit and look good.My running boards are flat without ribs.
