I upgraded my 68 from slave cylinder power, to late model power steering box. Not hard to do at all. My experiance with spacers was that the alignment with the steering col. was a little off & didn't like that. So I held the steering box next to frame to mark where the frame interfered. Then I heated up the frame at the localized area with a torch, & beat a dip in frame with a BFH. Only took about a 1/4" or less. I also had to clearance the radiator mount support to clear the power steering box. I think you'll find that the clearanced frame method looks better than spacers or washers. "my opinion"
