I have the foxbody 8 rib renegade setup. Bought a 12 rib crank pulley and a couple matching 12 rib head unit pulleys. The offset is entirely different. I assumed(very wrong) that I could simply swap pulleys from 8 to 12 and it would work. There's no way with what I have this will work. Do I need a different head unit bracket? Or remove spacers out of the mount bracket? Then my alt/water pump wouldn't line up. Please someone point me in the right direction.
