We have not done this swap but looked at both frames and it appears you will have to drill two holes in the frame to move two of the six bed to frame mounting points about 5/8". Other than that it should be a rather simple swap as far as the bed mounting is concerned. I can't speak to other problems you may encounter in switching this frame. Just purchase your remaining bed parts for the '53 including the wood blocks from any of the excellent vendors. When you pre-assemble your bed set it on your frame to determine where to drill for the mounting bolts.
