I *THINK* my truck is lowered in the rear 1", FROM THE FACTORY! Is that even possible? Right now, my front and rear fenders are 32" from the ground (I have some stuff in the back, weighing it down). But what makes me think it's lowered in the back...is the fact that, on the rear of the leaf spring, it has what looks like a small drop shackle! Do they come factory with that, or does the spring mount directly to the hanger? We're the original owners of the truck (it's a 75 Cheyenne SWD) and my dad said it's NEVER been lowered in any way/shape/form. Just curious, because if this is the case, then the drop I'm putting on it won't be as dramatic, will it? (I'm going 2½"/4")
