There should be 4 narrow strips of wood (ash) on the inside of each of the two sills. These are what the vertical sections of the running boards and also the inner (carpet covered) metal valances are fixed to. Original fasteners were 3/16" BSF round head steel machine screws with washers, the nuts being recessed into the wood strips. I don't think A7 running boards 1932-1934 were ever intended to take the weight of anything more than a child or maybe a young lady of average weight (apparently 8st pre-1950!).
