Modified Z-bar for Doug's Headers (pic)
I agree, mine had to be cut and re-welded. One of the arms gets flipped over, not going to do that with a hammer and vise.
Instructions are in the PDF I attached, it shows the difference between the stock and the modified z-bar. It's a really tight window to get it to clear. I labeled it for Doug's because that's what I have, but it's basically the same for the TTI headers. I actually think I downloaded this off the TTI site awhile back.
