for a long time the tall neck type rad. cap was not available. common
practice
was to take a rad neck from a chevy or ford or any other domestic
car and swap
the neck for a 3/4" type cap so you could easily purchase a darn
cap. saab ,
mg , healey even jap cars like datsun's had tall neck caps
fitted when new. you
have been blessed with some prior owner upgrading your
rad. go to any parts
store and ask for a 7lb cap and yer going to have the
fix for the problem as
well as the answer to the how and why this is like it
is.

[Spridgets] Radiator Caps
Jeff,
Did you try a cap from a later (crossflow)
radiator?
The neck is shorter on the crossflow rad and a crossflow cap is too
short to
seal a downflow rad.
