Around the flange that the turbo mounts on there are four bolts. The back side is difficult to access so Porsche has helpfully welded those two nuts to a strip of sheet metal so that they don't spin when you tighten the rear flange bolts. When I took mine apart the metal finally gave way as I broke the bolts loose. Call me cheap if you will, but $61 seems a little high for two nuts welded to a strip of sheet metal. I would like to just make one with my MIG.

Do I need to use stainless hardware here in this high-heat area? Should I be concerned about the longevity of commodity hardware? Let me know if there are any secrets to this Genuine Porsche hardware before I make what I hope is a sensible substitution.
