71 nova front suspension setup advice

[MC71Nova]

The SC&C stage 2 kit looks very interesting. A few questions. I don't see an X-Body kit.. did you use the Camaro '67 - '69 kit? Would that work for a '71 Nova? if you retain the stock lower control arms, is the tall lower balljoint a press-in or a bolt-in thing? Is that $816 price for both sides? It seems like this would get me much better camber adjustment and geometry, even if I use a stock height spindle. If I do that, what is the best way to lower the car 2" - 3"... springs only? Do the balljoints affect ride height? Would cut stock springs be better or lowered springs like a Hotchkis 2" lowering spring?
