That's for the info.
It's one more piece of the puzzle.
All the Best, Dirk
I think someone mentioned some SBC had them pre-72. Not sure on that, but the parts book would verify. Edit: I just checked, and 350 didn't have one. In 72 they did for TH transmissions, same as 402.

I'd like to pass on one that's for sure. If there's something to ethanol content, I'll never drive this truck long distances anyway. But then we're at the mercy of how long low-ethanol remains available.

With assys, the guide accts for 1000s of OEM identifications and part numbers, all written in short order. 700+ images include assm, illust., charts, and points of interest. Much of the info. applies to all 67-72 GM trucks, and to a lessor degree all 67-72 GM vehicles. My build thread, and more on the guide https://67-72chevytrucks.com/vboard/...d.php?t=730025
