I'm having trouble getting the '04 vette tanks to seat back far enough in the frame to allow the tank covers to contact the rear of the floor pan and the rear window frame correctly. Even if you tip the tanks forward to get the bottom edge to sit back more, this tilts the top forward and worsens the problem. I ended up actually putting a piece of 1" steel across the frame to give the tank a more solid platform to sit on. It also keeps the tank level. I bonded some padded insulation to the 1" steel bar and the rear frame member to cushion the bottom of the tank. I will probably use steel spacers between the bottom and top mounting holes of the fuel tank cover for a more sturdy connection. This leaves the issue of how to bridge the gap between the cover and the rear window frame.

Has anyone else found their '04 tanks don't fit? Any solutions?

Thanks,
EB
