Well other than the taillight wiring thats about it. As for taking the tanks out first... doesnt work, at least didnt for me. The way they are shaped, they dont fit past the curve of the lower part of the bed side. Just did this a coouple weeks ago. All I wanted to do was take out the tanks. Well now Im going to have a full body off resto. And make sure you get at least 8 guys to help ...LOL Or the correct way. Some sort of crane or winch from above. GOOD LUCK
