Look at this thread, http://www.grandprixforums.net/threa...k-in-here!!,it shows different brands of springs on cars. Like Russ said there are the Gr2's and they work great for me with B&G's. They are a little rougher than OE springs but not back breaking and give a great stance. Also do not get the shorter dog bones get the mount spacers, work much better for correcting the axle geometry.
