Mine came with seal.
This is what I got. It's not really AC Delco. It seems to be a GM part. I know AC Delco supplies parts to GM, but I don't know what the deal is with how this thing's packaged. It came with the seal and that's good because picture shows that it comes with a seal and the text says it comes with the seal. It is also stamped made in the USA. All good things. That's why I've given it five stars. I have questions, however, as to whether it's going to fit because the listing says it is 58.7 mm and it is stamped 54 mm. If it doesn't fit I will come back and certainly revise my review. Purchased for a 92 k2500 5.0 l. Edit:. It fit my truck just fine.
