Where to find a 98 3L y-pipe

[Tsestak45]

So I'm putting another brand new remanufactured motor in my truck because the first company's (whom I'm not allowed to mention their name anymore because of the lawsuit we settled) first engine made it 900 miles, second engine 3,000 miles, and the third and final engine 17,000 miles before a camshaft bearing exploded. Anyway my exhaust forever had a week where the wide pipe met them around folds because my original one was all pitted and rusted and I bought a fabricated one on eBay and the fabricator had the pipe coming too far up into the ball socket and so the manifold was hitting the lip and not sealing all the way. So I would preferably like to buy a brand new one from a reputable company but as far as I can tell nobody sells brand new y pipes for 98 3L. From all the pictures I seen it looks like the 4L y-pipe is identical but I've never seen one in person. I'm not talking about the ones with the cats built into it I'm talking about just the straight pipe one with the two O2 ports. Does anyone know if their interchangeable? And please don't give me all the same stupid answers of "I would just go to a U-Pull-It and get one" or "did you check eBay and Craigslis?" Or "just go have one fabricated at an exhaust shop". If I wanted to do any of those options I would have. I would like to buy a brand new one never been touched or used before.
