Longer torsion bar bolt?

You need a total of ZERO knicks or scratches, and once they are installed, they are indexed side to side with the numbers out the back where you can see them. Don't fool around. Put them in how they came out of the donor. Attention to clocking preferred.

PS: don't fear bigger bars. The spring rates stock are laughably soft, for that 70's 'cloud ride' bullshit they we're into back then.
