For just a 1" lift, you could make some shackle extensions... Stock, the CC rear is a spring-under set-up, so blocks would actually lower the ride height. I'm not sure if anyone makes a spring with a higher arch, but then you would also need to make a spacer for the shock...
-- The stock shocks have about 3" of travel. you could place a rubber bushing around the rod to limit the travel like a bump-stop.
