About 15 years I ago I cut the end off my 727 dipstick and brazed on the end to a GM dipstick tube and used their seal. Even with the dipstick unsupported it wouldn't leak. Later Dodge started using this style seal in their truck transmissions (early/mid 90's)



The boot style does work better but if everything is in good shape an oring works just fine.
