More torsion bar questions...

I have an original set of bars from my '63 Dodge 330, Slant 6, so they are probably the "lightest" bars that were made. They are from a original California car, and very clean. I can get more info on them for you if interested, Thanks...IMG_1552.JPG IMG_1553.JPG IMG_1554.JPG IMG_1556.JPG IMG_1557.JPG
