This is my new project

[brett281]

Got this 1967 C20 truck from my dad recently. He purchased it only one year old in 1968. The original owner had the truck painted maroon to match a camper he purchased for the bed.

The truck has the original 327 motor and 400 turbo trans.

My dad rebuilt the motor at one point and it has about 10 miles since rebuilt.
You will see in the pics of motor that the carburatur linkage is a little redneck engineered.

The truck runs, but a little rough.

Could someone please tell me what this part is near the carburetor. The white plastic piece snaps on but it is broken and the air seal compromised.

Just trying to figure out a part name so I can find a replacement. thanks
