swapability of sway bars?

yeah, i was really trying to talk myself into being a penny pincher. but the more i look at the reality of it, i'm just going to have to suck it up and spend the couple extra bills to get the good stuff.
i'm gonna call firm feel on monday morning. their stuff looks real top shelf. the mounting gear all looks really beefy. and its made in USA by racers. :-D
