alright as the title says its an 85 s-15 4wd with a 5spd now i belive the sticker in the dash says 4.10s...was this an option?? i need a new rear my old blew.. and i beleive it had 9,35 or 9.37 on it i put one in that said 11.40 but its the wrong ratio now i seen the rpo...post and i'm gonna look at those stickers but the question is where will i most luckily find this rear on blazers? or s-10s auto? stick? v6's? or 4's? i dont wanna pull a bunch of pumpkin covers... just hoping to find the right gear set and is the 4.10 availible in a g80 rpo or no??
