1969 c10 chassis upgrade ?

[Stephenshane237]

I have a 69 c10 build going on right now and need some advice on suspension upgrade. I know I don't want to ride on air so coil springs or coilovers is what I am looking for. I want to make sure that it is a bolt up kit, want to lower it 4/6 or 5/5. I will be running a new ls3, and I want it to handle good but ride quality is important. I have been looking at the CPP kit, no limit wide ride and trailing link, hotchkis tvs, and ridetech level 2. Any suggestions out there before I decide.
