Inline six power steering brackets

[Dwaynes56&68]

I am in the process of installing a six pumper in the 69. I need to locate a power steering bracket setup, and have gathered that they are difficult to find. I have also heard you can use nova brackets and van parts. But others are saying the later brackets wont fit right. Sooo, what car or truck will have the right parts? will the 73 up truck brackets work?
