completely rebuild front suspension?

I have a 73 Duster was originally slant 6 AC car and was told and no reason to not believe a 68 barracuda V8 K frame but retained the disc brakes of the 73 but did use the 68 V8 torsion bars. That I'm not exactly sure about or confirmed.
Honestly the front end feels just about as bad as it gets before something actually false off or breaks LOL so it's time to do something about it and I can't think of a better time than now with the motor and transmission out. I'm not exactly sure how to unload and take out the torsion bars and all that other suspension a arms I kind of get but I'm kind of back and forth on whether I ought to drop the whole K frame or not? Is there anything in there that I can't just do with it on the car? I know I want all the bushings pressed and pressed out and I'm not sure if there's some in the K frame? Will it be easier to take the K frame to someone or at least I can find a friend that has a press and do it myself which is what I prefer. And typical me I'll be using as cheap parts as I can to just tighten it up. And of course trying to do every bit of work myself as I know it's done right with my cheep parts.
thanks for any help....
