About 10 yrs. back I had looked and looked for a clean set for my freshly painted '85 W150. I bought some for a mid-80s Grand Cherokee (the full-sized one) and trimmed them to fit. Heavier aluminum than the originals and were only a few dollars at the local pull-a-part.
Someone mentioned that they were still available new (at least back then).
Edit: Found my original post. They stuck it in the tech archive.
