Hi. Can anyone tell me the GM part number for the air manifold assembly (smog system air injector pipe) used on my 1968 6 cylinder engine? Thanks.

Thank you.

Just to be certain of the part number, I'm including a picture of the part from the Service Manual. Sight unseen, I don't want to order the wrong part. Can anyone verify that 3918952 is indeed the correct part number? Thanks.

I don't know where you'd order it - that part was discontinued about 30 years ago.

Thanks for all your help. I just received in the mail the last GM inventoried 3918952 air manifold assembly from a Chevrolet dealer in Arizona.

Well done !

Can you post a picture of the NOS item.  I'm reasonably certain that the colour is original on mine but would like to be 100%. I'm assuming that the finish between a 67 and a 68 will be the same.

Thanks

Here you are. BTW, am I correct in assuming that the pipe was made on December 3, 1975, 75L3?
