IN WTB Exhaust Manifolds with Smog Tubes - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**DANTIP** · 06-09-2011, 09:20 AM

WTB '72 1/2 ton 402 exhaust manifolds with the tapped smog fittings. Ideally, I would like to have the smog tubes still attached/threaded into the manifolds, but most were plugged. If smog tubes are gone, I prefer the plugs removed. I have an urgent need for one set but would buy more if they are out there.

What's out there?

Hi Dan, I'm pretty sure have at least one side in NOS and maybe a pair. I'll check for you later this morning. Thanks, Sharpie

Thanks Dennis!! Let me know!

Hi Dan, looks like the NOS ones I have with tubes are 73-up. I can check my used ones if nothing else shows up. Thanks, Sharpie

Dennis, those are beautiful but I agree the tubes look like 73-up. Here is a pic borrowed from another post that shows the manifolds with tubes along with a pic of a set of bare tubes. I hope to be making a deal on the set shown but will buy as many sets as I can get ahold of.

If anybody has a GOOD set, please PM me.
