I am buildin a leaf pack for my SAS out of IFS rear (7)leafs. ARE THE PICK-UP LEAFS A DIFFERENT LENGTH THAN 4RUNNERS?:I have a 88runner and plan on useing the stock rears with another pack to use in the front. I have a free donner set from a 86 standard cab 4x4, but I have to drive awhile n pull'em. I can't get anyone to measure for me. Mine off the 4runner are 48"
