c10

Hey guys, i have a 79 c10 and i am wanting to see how low i can get it without z'in the frame.I saw 3" drop spindals...is that really better to have than 2"?? Also...if i re worked the tranny crossmember and linked the back would the get me any close to the ground? Anyone got any pics of a c10 layed out but not z'ed?

mine isnt body dropped or z'd and i have stock spindles/control arms, with the notch in the back it sits about an inch or two off the ground laid out
