86 Nissan D21 SE. I need help identifying parts.

[MyD21SE]

I have no clue what these parts are. Can someone help me?



They are in dire need of replacement. As you can see from the severe corrosion. Any help would be appreciated. I would also appreciate any recommendations on where to find replacement parts.

Both are part of the pollution control or emissions system. I had to buy the top part years ago and it was expensive for what is it. That is likely going to be a dealer only item and I bet its NLA. I don't recall what the name was. I have no idea what the bottom part is called. I don't have that on my truck because I have an XE.

Might have luck finding them in a junk yard.
