Need Advice about steering

Here we go again I had my front end re-done about a year and 2 months ago, Well Last weekend I just got some new american racing rims same size and everything like oem style. Now I am having a problem with the steering as it drifts to one side like the alignment is off. Sinces I bought the car like 2 and 1/2 years ago I havent replace the steering compont yet, Thats the background , so my question is how hard is it to replace the steering compont? I heard if you measure the steering knuckles from the old sleeves to the new sleeves, the alignment would be somewhat close, to drive it down to get it done right. Is that true? Can anyone give me advice on removing the old steering componets?

yea I did get a date to get it aligned but I did go under and the joints on the steering linkage is crack looking. So I might have to replace the linkages
