A little further: Thinking I could fit a 33X12.50X15 tire there
Just kidding
Here's the 67 Camaro section I spliced into my tail panel; Thanks again to ItDoRun for the panel section and Scherp69 for the idea

I think I inhaled some paint fumes that day because I kind of messed up the cut. Oh well, it's a learning process, right?
I did add more weld to fill the gaps after this shot, just can't find the picture.
I also started cleaning up the underside and prepping for epoxy primer, then Raptor liner. Pics on that soon.
