ive been told by several people to run 67 impala rear shocks to accommodate for the 4" of drop i have.

i cant seem to find a bilstein that crosses to that though, any suggestions?

 

Get hold of the guys at Calvert - they'll square you away. I have their adjustable load shocks on the back of my '04 (same drop) and they're pretty reliable. I can still carry loads in the truck with the turn of a dial and they ride pretty nice on the street with an empty bed as well.
