Obtaining a 17.734472 MHz crystal in America might be a problem, so you should probably swap the crystals as well. (The 14.318181 MHz crystal can be found e.g. in PC clones.) And note that you should get a 6567R8 and not a 6567R56A if you want to run all demos. The older revision produces 262 lines and consumes 64 cycles per line, while later revisions produce 263 lines by 65 cycles. By the way, it's not completely necessary to swap the crystal or to touch the jumper that selects the clock divisor. The clock frequency does not matter unless you want floppy speeders to work properly, or if your TV does not otherwise synchronize to the video output (or if you want the SID to produce the music frequencies correctly).
