dsapper, I admire your build. This is the build I wish I could do but don't have the resources for. I wanted to add comment about the bracing that may be more relevant to those reading this thread. First comment is that you can take the front GP frame brace and mount it more forward with new mounting holes. I had to do that because my stretched SLIC was in the way.
I was wondering about the braces outlined in light blue for the wheel well area of the frame. Are you using those? What car do they come off of? I'm doing everything except for the cowl to fender braces. Thanks
