mopar PS box and UCA questions

[dusterbd13]

ok, so the duster wasn't aligned. the alignment guy actually refused to do it due to a slightly bent upper control arm and a severely worn out steering box. the really sad thing is, i didnt notice either in the restoration. i honestly thoght that a mopar PS box was supposed to feel like that.
so i am going to replace these parts with aftermarket pieces designed for greater driving enjoyment.
i am looking at street oriented tubular upper control arms. that means bushings, factory ball joinys, and no cutting necessary. at last count, i saw like 4 different manufacturers making this style. whise should i use, and why? what benifit will i see from these particualr arms, and will they do anything funky to the front end geometry on a 73-up a body front end?
also, there are two companies that i am aware of making PS boxes in a performance design, steer and gear and FFI. what is your experience with these companies, and what feel would you reccomend. i am looking for a steering feel much like that of a C5 corvette. heavy, but not qite manual, with almost no dead spot on center. are there other manufacturers i should look at as well? i dont want to go rack and pinion due to the build style of the car.
so please, offer experience and advice.
thanks
Michael

Firm Feel has both the tubular uppers and the steering box you desire. Check with them about the differing levels of firmness and how best to meet your needs.

Go manual. It will be fine on a light weight A body.

On the surface, yes that may be possible, but additional caster and significantly wider tires could easily turn a manual box into a bear.

Stock control arms are easy enough to find if your on a tight budget. Combined with the Moog problem solver upper bushings and you could easily get a lot of extra caster, unless your set on using poly bushings in the upper arms. Another alternative would be to have a set of offset del-le-lum bushings custom made from one of the sources here on the board.
