New springs or a different rear end? Looks good. My white 94 with Monroe severe service shocks is sagging bad in the rear when sitting next to my 95 with the air shcoks. Im gonna try and see if i can get that air suspension hooked up again.
all other stuff is being taken care of tuesday. no need for the 94-96 m/c and prop valve, 79-80 trans am WS6 4wh disc master cylinder is a direct bolt in for the caddy and i've got a direct replacement disc/disc combo valve.
front stuff being done this week:
impala springs to match rear
summit extreme performance drilled/slotted/plated rotors(they were on clearance for same price as stock)
tie rods, idler arm, center link
SS/9C1 quick ratio steering box
HA sway bar(SS bar in rear)
new calipers, pads, hoses
