TH400 vacuum line - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**ThreeQuarter** · 05-12-2020, 02:00 PM

After searching many a thread for an answer, I can't seem to get confidence around finding the correct steel vac line for a '68 327/TH400. Can anyone show me some pics, especially ones that capture the top end of the line and how/where it ends and transitions into a rubber vac hose?

I've also been shopping for a new one from an aftermarket supplier, but nobody's application guide seems to list parts for a '68ish GM pickup. Wouldn't one from a car in this era work OK? ...but they have many different part numbers for the different GM cars in these years, so maybe not? Can anyone give me a part number that will work for my pickup?
