Power stearing swap

Has anyone installed power stearing on a manuel stearing Tracker. I have a 94 with manuel stearing as a daily driver and a 91 with power stearing that i intend to junk. Will I have to change the stearing wheel and collum? or just bolt on the pump and change the stearing box?

thanks

you would not have to change the column, just all the necessary parts (brackets, hoses,pump, gear etc.) to the 94
