Hey, you may already may know it, but it will not just bolt in it has spring perches for a coil sprung truck. So you would need to weld on new perches. 56 1/2 seems a little narrow mine measures 58" backing plate to backing plate. That may just be difference in where we are measuring. As far as strength I believe the weak spot is the c-clips but companies sell elimination kits for those. Here is an article with a comparison between 12 and 9, some good info
