In my humble opinion you are 100% correct. RFC1 and 2 are a very tight fit when all other components are mounted properly. I believe that they used to be on the bottom of the PCB, but were moved to the top for very good reasons. I wonder whether some Plumbers' Teflon Tape (the thin white stuff) put around crystals X3 and X5 during installation would help prevent shorts between choke and crystal can.
