Its possible, I had a set of draggin motorsports upper and lower adjustable control arms with those sperical chrome moly bushings, but they are really more for drag racing, not for handling. They are also noisy. I still have the lowers out in my shed, but you can't use a rear sway bar with them, no bracket for one.
LOL, they might rattle a little bit, actually I don't remember them rattling on my 94 when I had the draggin motorsports one on there. Global West is a very well made product from all I have heard, you should have good luck with anything from them. I am still debating on upgrading to their subframe connectors, not sure how much trouble cutting the ones off I have on there will be.
There was no way to pack the type on the draggin motorsports control arms in grease, it would just fall off, there was nothing to hold the grease on there. About the best I could do for those was spray a little white lithium aresol grease on them now and then.
