Torsion bar upgrade

If you have any yards w/old A-bodies, the best candidates are ones with V-8's and A/C. The ends of the bars will have 3 numbers. You want to see 892 and 893, those are the fabled "340" torsion bars. Slant cars with A/C sometimes have the bars as well, and good luck finding a 340 car sitting in a yard...be sure to look under any and all A-bodies, because some came w/HD suspensions, too.
