No. But honestly I didn't see one during the tear down so maybe it wasn't ever there.Lower dipstick guide tube....keeps the dipstick from curling into the crankshaft, leave it out and the tip of the stick will get repeatedly hit and typically breaks off right at the "add" line imprint.
If you search, you can probably find a better price,
It's an odd diameter....3/8" hard fuel line won't fit, 5/16" will fit but is sloppy in the hole, it can be used in a pinch if you have to make your own since the upper stick tube traps it in place.

Machine shop didn't give it back to you?
He said it's from a 70s Camaro.All the 8.5" 10-bolts have a 30 spline pinion stem, but what you really need to know is if the axle spline in the posi is 28 or 30....28 is stock in the 8.5" Nova rear, 30 spline didn't arrives until 1988, and while it can be retro-fitted to the earlier rear it requires you to replace the axles with aftermarket 30 spline units so the spline count matches.
Add reads like it is 30 spline chunk, so it would not work without replacing the axles....but you might want to confirm the seller actually knows what spline to count, he may have just counted the pinion spline.
You'd also want to find out if you can what brand it is, so you know what type clutches it has and whether it could be rebuilt if needed. ...Cone clutch Auburn differentialss can't be rebuilt.
it wold be worth it if the spline matches....but i have a suspicion it is out of a late model truck, so it would be 30 spline.
Impressive!I just noticed...it is a 12-bolt chunk...not a 10-bolt.
Look close, two ring gear bolts in every rib divided section, you can see 10 bolts in the pic and there are obviously 2 hidden from view by the bearing .
12-bolt are 30 spline axle and 30 spline pinion.
No go in a 10-bolt housing.
Any stock 8.5" 10-bolt posi unit from the 1970's will be an Eaton clutch style, and have a flat wave preload spring in the center, not the two seperate plates and multiple coil spring preload pack like the 12-bolt and the auburn diffs have
