73 Dodge Dart Steering Box, Idler and Pitman Arm

Hi All,

Went in for an alignment and they say I need an Idler/Pitman Arm and Steering Box. I'm sick of people just telling me to get new parts, this lazy today attitude is killing me. Is it really necessary to get new parts if they aren't worn? I assume you could replace the bushing on both parts. Of course the steering box, if the screw is already turned in all the way, is shot, and a rebuild is too difficult. So that would have to be bought.

And how difficult would it be for me to replace/repair these parts myself? Then get an alignment.

Thank you
