1968 turbo 400 dip stick tube help needed?

[jasonL78]

Looking for a little help with a 68 turbo 400 dip stick tube? Has anyone bought one recently and had good luck with it not leaking. I bought a chrome tube off e-bay with an O- ring, when the O-ring is installed in the groove it wouldn’t fit into the hole.(It just slid up the tube like the groove wasn’t deep enough) I tried a smaller O-ring and got it to fit but it is still going to leak I think. Don’t really want to take a chance. Does anyone have a picture I can reference it to? Any help would be appreciated.
