Hey all. Just picked up a 12 bolt with multi leaf perches. What rear leaf springs do I need? I am running a mono set up now. I would like to not run a spacer between the housing and the spring. I saw JC Whitney has replacement springs, but I dont know if they are 4 or 5 leaf. http://www.jcwhitney.com/replacement.../p2005965.jcwx
Will these work?
