I was reading that when u weld the frame stiffiners to the unibody that it creates a weak point at the welds and that over time with flex they start to crack the unibody?I'm gettin ready to buy them and i dont wont to if its going to crack it.

oops, read it wrong, that thread was about welding to the unibody.

Use plug/rosette welds and then stitch weld the edges. My understanding is, keep the heat as low as possible to not create weak point, but high enough to penetrate.

Welding just creates weaker (but not necessarily "weak") points.... it's the heat tempering the metal. If you weld it up right, you shouldn't have a problem though. it shouldn't make it so weak that it is prone to breaking.

Just bolt, nothing to worry about then if you use the right hardware.

Let the welds cool on their own as well. DON'T use water or wet rags to cool down each stitch weld. This causes the metal to become more brittle, rather than flexible.

sounds good. I'll probably add some frame stiffeners at some point in my XJ's life...
