78 C30 steering box in my 68 C30

[My Alter Ego]

I've read a number of threads relative to this swap and have come to the conclusion that this is in essence a bolt in situation. My 68 has power steering as does the 78, but the articles I've read don't discuss which power steering pump assembly is/are being used. I'm swapping out all the front suspension from the 78 to install on my 68, but the 78 has a Hydro boost p/s pump, Is it advisable to continue using the pump from 68? Thanks in advance for any and all info.
