Finished off the battery box by deburring and riveting the bottom shelf extruded L-angle to the firewall using 5 steel rivets.
Finished installing the dual fuel pump frame by deburring, filing and riveting the assembly using 4 steel rivets.
Fitted the voltage regulator cooling bracket over the regulator/rectifier mounted to the right side mounting plate. Also fitted a 1" aluminum flange to the cover for securing a 1" scat hose. Once everything was fitted, I updrilled all the holes to final rivet size (A4), deburred, filed, and sanded all the pieces, riveted the flange to the cover, then riveted the cover to the inside of the right mounting plate over the regulator/rectifier.
