first pic: i think your referring to the inlet pipe. These will probs be T30 and be the exact same as the lower Left boost pipe bolt (as seen in pic 3) Guess the right hands stripped and don't think that's the correct bolt either.. but it might me.
If you remove the lower left bolt from the silver boost pipe, take that to TPS and ask for 3 of those then that should sort you out. But they will also guide you to the bolts you need if you tell them where you're missing them from.. show them the pics too.
as for the under tray bolt, take one of the others out.. take that with you to TPS and ask for one of those too. Should all work out nicely for you mate.
