PST 1.03 TORSION BARS

All my bushings are

The front was done 5 years ago every things new all front and rear are all poly bushes ,new upper & lower ball joints , tie rod ends, rods, pitman arm, Idler arm, rotors, calipers redone with new seals & pistons even had my front hubs made to run LBP wheels and still use the Kelsey Hayes calipers. Front is tight steers well. what did you use to take some material off, lath, file, flapper sanding disc ?

I used a 4" grinder, and theres no way you are going to grind on it so hard as to affect the temper of the bar.
On another note, PST quit making the zero clocked 1.03 Mopar bars some time back.
