I am surprised to see that too, Don. I noticed that the product number starts with a "70", instead of the "60" as on the windlace style weatherstrips. I also notice in the next column to the right and just a bit lower is a "70" prefix number for a suburban rear door. I'm making a supposition, but I believe that the "70" numbers shown for 39 and up doors are for the rear doors of the suburbans, panels and the canope expresses.
A call to Steele Rubber Products would probably answer the question.
