SOLD 
I'll just close this thread.
With the DSE Quadra-link on the way, I'm selling the rear suspension parts that I won't be needing. I'd like to sell these parts together, but if I end up splitting it, Payton gets first chance at the leafs.
I'm asking $600 (plus shipping) for the partial kit which includes:
DSE offset shackles and hardware
DSE 3" drop leaf springs
DSE Koni mini-tub shocks
Shock mount plates with 1/2" U-bolts
Installation DVD
What's missing:
Deep tubs, crossmember, adjustable perches and upper shock mounts. Those parts retail for $550.
For reference, the complete DSE mini-tub kit retails for $1300 plus $210 for the Koni shocks, which brings the total retail price for the mini-tub kit from DSE to $1510.
