Since the Camaro and Nova front suspension was and still is used in round track racing applications, there are numerous choices available from places that cater to the roundy-round guys. All sorts of different ride heights and weight ratings can be accomodated by simply selecting the spring height and weight capacity from an online catalog. Just Google "race car suspension" or something similar. ARP (American Racing Products) is one of the bigger-name suppliers, but there are a bunch of them.
