Leveling kit on a 1990 f-250?
 

With a ttb axle? It also has some weird reverse leaf springs. I'd really like to swap in a solid dana 50, but I don't have the time or money for it considering it needs stuff just to pass inspection. I was told blocks would mess up the geometry... Ad a leaf? But it is not a normal style of leaf spring... I guess I'll just end up running it as is until I get more money.

blocks are fine. just not huge ones
