does anyone know why some lowering springs say they are for only82-98 and others say 82-04.

 

I think there the same thing personally!! I don't believe there was a difference on the 2wd's but I may be wrong! The difference your seeing is it between two different brands I find that as a common thing to see. What year is your's? If you go to streetbeatcustoms.com they have a few nice kits to choose from for a decent price!
