suspension/frame differences between 6 luggers and 5 luggers

I know this question has probably already been asked, but what are the differences between the 5 lug and 6 lug suspension or frame. I know the six luggers have the leaf springs over the rear axle instead of under, like the 5 luggers, and the front struts are longer I'm guessing, but what are the other differences? ie UCA's, frame, etc.?
thanks

 

the ucas the lcas, the frame the spindle its all different



6 lug


5 lug

 

wow, crap, that's completely different. what are the best front suspension options for a five lug if i want to get it lifted a couple inches? other than a fat bob's or readilift spacer option

 

Also, could anyone tell me if this setup would work?
2.5" SAW's up front (stupidhurts has those on his 5 lugger, so I'm guessing those'll work)
TRD bilsteins in the back with an axle under springs mod?
