(question: part fitment) 68 Valiant /6

Looking to buy this pump for a power steering conversion (from manual to power) for my 1968 Valiant /6

The website says it fits 69 and up.
Should I have any reason to think that a /6 Saginaw style bracket would not fit my car, and mount to this pump?

I can find /6 brackets online, but they don't say specifically what year
