I like the boot seals that the later transmissions use.

You can't use that without modifying the dipstick.

when I put together a 727 I makes sure the dipstick hole in the trans and the dipstick are oil free , put on the o ring the tube and put a big bead of copper type RTV around the tube below the o ring , put the tube it and let it sit over night in it's secured position , no leaks .
