Right I am back again with probably some more stupid questions

Because of busy weekends I have been unable to fit my custom induction kit however I have a long weekend this weekend and think I will get some time to do it however I think I have missed some parts so hoping someone can help me.
The parts I have are:
1 x Carbon Fibre Airbox
3 x small Jubilee Clips - Think I need one more but can grab one easily this weekend
1 x large Jubilee Clips - I presume to clam down the Airbox
3 x varying size hose joiners - think one is a 76 to 67 reducing hose joiner - SO might need another one which apparently is just a 76mm hose joiner
1 x 90 Silicone hose joiner - think this is not needed for my setup
So apart from the couple of things above following the guide below I think I am also missing a 90 aluminium bend
