need a leaf spring.

[bignick33]

hey guys i have a 1998 dodge ram 2500, extended cab, long bed. About two years ago a buddy and I added about a 2 inch lift, by shocks and springs for the front and a lea for the back. Well the leaf in the back has loosened up a little bit causing the back end of t truck to be lower the front. Does anyone know where i can purchase a leaf spring for my truck. Thanks, nick
