Congrats on passing the WoF Ash but i'm curious about something - what are you calling wing nuts?
That's what i've always known as a wing nut, can't see how that would ever be included on an exhaust/turbo set-up as it won't take the torque (or heat!) so i'm guessing it's something different that is known as a wing nut in NZ? Perhaps what we know as an Aerotite nut?
Meant to ask earlier when your first post appeared but forgot................
