Lowering rear to level truck

[crawdad]

LMC list a shorter rear spring shackle and it is my understanding that it will drop the rear about two inches. My 85 SWB sits up real high in the back, ungly as all get out. I don't want to lower the whole truck, I'm not into that scene, but I do want to, more or less, level the truck out. Do you folks think these shakles might do the trick for me without screwing up the movement or function of the rear leaf springs? Thanks for your opinions.
