PFR brought this to my attention, I never noticed that the play-by-play of the 1958 championship game
credited Lindon Crow with the interception of Unitas
Carl Karilivacz got it --- and replay shows it and newspapers at the time

I am having trouble attaching files --- and they are right size, but cannot attach
but looking at the clip and the papers it was Karilivacz
