Two waste gate solenoids an egr stuff

[Hotrodbuick]

I have two waste gate solenoids. One is brand new in the box and the other is used an has one nipple broke off. An I have egr piece, not exactly sure what its called but I know it goes to the egr. I have the egr valve some place just can't find it right now.

Ill take 50 for waste gate solenoid with broke off nipple
Ill take 100 for the brand new one
Ill take 20 for the egr piece
