Had the whole day on the truck :thumb2 One of the jobs I did was to weld up the box. Did that and then added in a little bit extra to complete the flange 
Then trimmed it square and scribed to suit my back end :lol Drilled through and marked the floor.
Rivnuts and anti corrosion grease , as all these fixings are right over the tank.
All sprayed up with more stone chip grey
Then bolt the begger down. I'll make a gasket for it eventually.
Last thing then just another coat of paint , job done :clap
Also extended the tank breather up to roof level while I was there. Next job will be to do the fuel filler tub .
Onwards
