I'm not afraid to change a design when it isn't working. There was a part of the interior and inner frame where they overlapped and created a 1/4" thick segment of rail. While I acknowledge my offroad fabrication past, this isn't a stunt car and doesn't need 1/4" rails. I segmented the two plates and replanned my weld steps, and added about 1.5 lbs of lightness to this little bit of of the project.
Rev1 inner frame plates tacked and cleco'd. I'm building the top and lower plates today and this week.
