The sides have pulled in making it difficult to get the center down. Rand Robinson alluded to the possibility that the tank would be challenging to assemble.

With the flanges already glued in and by using pop rivets to hold the top down this was less difficult than it first appeared. Second coat varnish front of firewall.
