I've got a 37 pickup and have had some pieces of Steele Rubber on my truck as long as 15 years with no cracking, discoloring or decomposing. I highly recommend Steele Rubber and if you call them they might send you a free catalog.
When I did my truck I carefully went through their catalog and pinpointed every rubber part I needed for my truck in their catalog. They had every piece I needed to do my 1/2 ton pickup and I found their quality to be the very best.
