I don't know how close we are to OE on the OD to be honest. I'll check it when I'm back at the truck. Because I do have the invoice with me, I can tell you the NAPA part number is H-457. I couldn't get that to come up as a good number just now over at NapaOnline when I went searching for specs. But I bought it from, shall we say an 'established', NAPA...so it's conceivably old stock. But my method was simplistic, "here's my OE tee, what fits?". I'll try and get you better info today or tomorrow on the OD.
