Kelsey Hayes brake spindle?

I'm sure it's in here somewhere. I have the 5 on 4 Kelsey Hayes disc setup, which I got when I bought the car as extra parts. Which none of it can be used. I'd like to go to a 5 on 4.5 bolt pattern anyways. I understand that I need the 10" drum spindle to convert to 5 on 4.5 bolt pattern using large ball joint setup, which I'm going to. Will these spindles work or are they wrong ones?
Thanks in advance barracuda newb.
