I fitted the fuel bulkhead fitting doubler as per the FWF drawings, but now that i have come to fit the battery box and relays I have another interferance issue, The starter relay will have to move up slightly this will entail moving the platenut up also using the existing top rivet instead of the lower one, This brings the bottom rivet very close to the doubler rivet but it only holds the nutplate so I am not to concerned.
Drilled and deburred the lightening holes
Fabricated all the components
I fitted the fuel bulkhead fitting doubler as per the FWF drawings, wish I had waited now
