If you want new springs, General Spring in Olathe, KS has new springs for each different configuration. I believe they have 6 different part numbers. Most of the springs have a 10.5" installed height. However, there are two sets of springs that have a 9.0" installed height with a similar load carrying capacity. http://www.generalspringkc.com/index...arent=421&pg=1 Part number 8088 and 8090 have the shorter installed height. I think this will get you what you want. Also, they have 10 sets of 4 leaf rear springs in stock as of this morning. I just purchased springs for one of my trucks from them. While I had them on the phone, I asked about our cars. I do not work for them or get any kickbacks from them.
