Pitman arm is hitting tortion bar! Help?

I was thinking an exhaust manifold set something like the Ebay one below.

This is GD Musclecars out of Florida and they have a bad reputation and their stuff is overpriced. So this $325 is high water mark. I'd think you could do much better. $250 maybe even lower if you shop.

Do not buy these:
