am i correct at thinking that the 85 iroc's ALL came with 3 series carriers? if so i have the chance to get a rear for about 80 bucks......was wondering if it would be worth it to switch out rears to have a 3.23 ....was thinking about later on down the line putting 3.73 in it due to it being a 3 sries carrier already --at least im thinking 3.23 was 3 series.....not 100% positive so if im wrong, i wont be suprised

would i see enough of a gain from going 2.73 to 3.23 for this to be worth it , or should i pass the deal up
