68 GT convertible project

Looks really great. Like a factory install. I did something similar with 2x3 14 gage and overlapping on the outside of the rear framerail, but I have a steel roof for stiffness. Not as critical as a vert. I had to remove butchered in subframe connectors by a prev owner, and redo it. The fwd parts of my rear framerails were butchered from the prev install. Had to clean up, and cover up lol. Yours looks really slick. Nice clean install. Ditto on the drain holes. I will have to slot my rear floorpan when it goes in.
