Why so critical of "universal" flex radiator hoses?

I remember those Family-First days like they were yesterday. Oh wait, it was yesterday! In today's topsy-turvy world, they never really end. My 68 is languishing in the carport, cuz I give all my spare money to the 3 little Beggars I fathered. Hyup, it's still Family-First.
If I don't drive her this summer, it will be the third no-drive summer. She's needing body work pretty bad.
