The gears in my head started turning as I'm couched with pneumonia. I wonder if I take the bottom skin off the bad 77 tank and put a good tank skin from a 79 tank? In order to make a good 76/77 early tank. I now have a good 77 tank, but hate to throw away the bad one. I need to look at the bottoms of both style tanks. My 79 has pin holes on the top, so its bottom is the perfect donor. I know I don't possess the talent to do this, just the thought. However, there are a few people I know who can do this. I know my dad could, but he could weld anything. As a kid I watch him remove his chevelle's tank and fill it with water and weld up rust holes on it. Going to take some measurements and compare tank bottoms
