I took a photo and then I removed the heat shield and tested fitment without it and it was closer to fitting but still no luck.
Here are the photos....
This is with the heat shield obviously. I have a loose bolt in the first flange to hold it in place, the rear of the manifold is sitting about 1.5 inches above where it needs to be...
Now here is a photo with no heat shield. It's close, but no cigar. All of the bolts are in, I started to tighten the bolts but the collector flange is binding on the upper frame rail from below.
