56\" rear springs I want to put 56" rear springs in the back of my jimmy but I have some questions? Frist, where can i get some flexy 56" springs? I want to flip my shackle flip but is there anything else i need to do? (move brackets back, longer shackles, ect?) How much will i have to move my rear axle if i have to move it at all? Do i need a 1ton shackle and flip kit to use with the 56" springs? How much lift am i looking at with 56" rear springs?(I have 6" and i don't want to go higher) What kind of flex am i looking at with these springs?\ Any help would great, thanks!
