**planning ladder bar set up**
by no means am i an expert here, but i would go with a 4 link if your going to change from leafs, otherwise id go with the caltracs or SS springs...ladder bars work no doubt, but like already said i dont think they are a very good idea on a street car...but thats all subjective...my buddy drives a 4000lb big block minitubbed chevelle with a ladder bar rear all over the place (and trust me our roads are BAD) and he hasnt had any problems in a LONG time, but i wouldnt chance it
