Mystery parts left over from desmog - can you name them?

[FJ502]

So I have some extra parts after my desmog. Do I need any of these?

#4 looks like it goes on the carb but there is already a gasket on there

#7 looks like it was a spacer for the intake/ exhaust but I made some custom ones with washers

#5 looks to be a ground for something

Am I forgetting to bolt something together with any of these parts?

#4 is the gasket for exhaust modifold flange

Ahh cool - glad I don't need that one (got headers now)

5 is the temp sensor for the carb cooling fan.
Could 1,2,3 be the bolts that clamp the egr cooler to the block?

Yep - I think your right. So the bolts can go. I'll make sure to get #5 hooked back up.

Number seven could be a nuffle trunion, but you can never be too sure.
