Who makes front springs that are at impala height, and sold seperately from rear springs? Following the all-knowing AutocroSSer's advice, I have decided to use stock 9c1 springs in the rear, so I now I need something to go in front. I'm looking for something no heigher than impala SS, brand new, and in the price range of maybe $70-ish. That rules out OEM parts. What does Moog have?
