i lowered the front of my 1990 1500 scottsdale and im stuck on how to lower the rear of the truck... im on a really tight budget... i heard from a buddy that you can take one leaf out of the leaf springs but im lost... thanx for the help  

Taking a leaf out will lower the rear, but will make it softer. I would look at getting a Shackle kit..  

where can i get the shackle kit and how much do the usally cost... i would probably take a leaf sping out but i cant get the damn things off   .  

There are tons of sites that can help you out. Try Godfather customs
