The battery box kit also came with master and starter relay mounting hardware and brackets, so thought I would finish that up. Made the doubler per 31A plans and then found it could not be used as it interferes with fuel penetration called out in OP32 (fuel injected engine details). So made some alternative doublers instead and chose a slightly different mounting location.
