EGR cooler delete missing parts?

[Hanging_Heels]

So im going to be doing this Sinister EGR cooler delete when i do my ARP Head studs as well in the next couple of days. I bought this kit used off the classifieds here but it came missing these things. Could you guys confirm for me what these are called and where i could get them from (i.e. Home depot, Ace etc.)? Thanks

1. I think this is a spacer but can someone confirm and tell me where its used?
2. I think its a 3/8 barb fitting?
3. Are these just fittings to hold hoses in place? Do i really need them?

Heres what i was given.

Do you think i should get a new gasket as well, or should this one be fine?

New gasket for sure. The rest I've never used on a 6.4. All I use is a couple bolts, 2 coolant plugs, and a blocker plate for the exhaust, oh and an intake elbow.

White_monster youve been my hero lately, you always got answers for me lol... Do you think i could get that gasket from auto zone or napa if i bring it to them? What exactly does the intake elbow do? Do you think i need it right now?

 

[White_monster]

That gasket seals the exhaust from leaking. Go to ford, I have reused them but I don't recommend it. The intake elbow just cleans things up but it's not a must do at this point of time.
