Add-A-Leaf is the best idea IMO......My 94' had 6 leaf springs in the rear....And it rode and cornered great.......The extra leaf seemed to stiffen the rear "Just" enough....

P.S-Bill-If you do the add a leaf system, it'd be a great time to swap those worn out shackle bushings for some Polyurethane Bushings....
