Thanks for the reply! Ya I knew DrDiff had them . I am going to go with a B-Body width rear end also.
What do you think about either spray on bedliner or rattle can rubberized undercoating to protect the composite springs from rocks etc...?
For my set up I was thinking the 175Lb rate? Hotchkis sway bars 1" t-bars, bilstein shocks....

Just thinking about the extra 1/2" .... if it was a issue ( which I doubt) one could fill in the holes and drill them 1/2" forward no?
