swaybar question with 11 3/4 brakes

ok so I called addco :read2: to find out how theirs mounts........and its also using the shock bolt....and i supposidly may have to buzz the corner of the mounting tab ......... seems from pictures the firm feel setup looks the best, but just the front bar costs more than both a front and rear with shipping from addco.........has anyone used addco and not been satisfied, dont get me wrong, I like the firm feel setup, but I cant justify 3 times the price if another will get the job done
