On my 72 Supreme 350 4bbl, how do I remove the green plastic AC thing on the inside, and the side plastic vent tube thingy on the inside/outside? I am getting all my parts bead or soda blasted. Thx.

 

If this is the green thing it's fastened from the outside with some clips.
The other thing should be held in with a horseshoe clip on the inside.

 

I managed to pry it out. The two vacuum nipples seemed pressed into the clip on the bottom. Where to get a replacement? It is some kind of sensor?

The original vent tube though I had to rip out as it was hard like a rock. I see Fusick sells replacements though.

 

It is an air cleaner temperature sensor. It was held in by push nuts. New sensors are still available and they come with pushnuts(see pic in my prevoius post)
