power steering

[firefighter2134]

so now my wife wants me to put power steering in the 69 that we have. i already have purchased a 4 turn ps box out of 78 f150 and the power steering pump and brackets. i still have to get a double groove crank and water pump pulley. i guess what my question is will i have to change the steering linkage underneath? if so should i just go with heim joint steering? i could go buy some dom tubing and buy heim joints and weld it up myself maybe save a few bucks? any help would be appreciated.
thanks
