That is a real good point on the tbars. Actually I will be doing 2 of em, One a BB (& not sure how much aluminum will be on the eng) & the other a SB daily driver. I kinda wanted to nab the sway bar for $80 before somebody else does. Here's one & I ain't got another one yet.
Plan on doing some fabbing with Addco bars.
I think a front sway bar is almost always worth it. With the small early a-body, and no other changes, a factory bar or the smallest aftermarket bar will be a decent match.
JCC's summary is absolutely correct and the third point worth keeping in mind whenever faced with a pitch to make the suspension more rigid.
