There is no known source for the linoleum mat for the suburban at this time. There was a guy several years ago that was testing the waters to see if there was a demand for the material made to fit. He has disappeared from the board and I don't know if he ever produced the mat for our use.
You can make your own mat but it won't be cheap or easy. You will have to find a supplier that will sell the mat in brown/tan and the width needed. It has to be thicker than many of the products available. Then you will have to make a pattern from your floor, including the cut-outs for the seat mounts. You will have to set up a jig to route the grooves using the proper router bit so that they will look like the original pattern.
There is a guy that posts in Hemmings that make the matting for the chevrolet Nomad and other models that had similar matting, but I don't think he has attempted to make the matting for the suburban.
Good luck and if you find more information, please share here, there's lot's of guys that want the matting for there trucks too.
