Has anyone else changed over to the FX from the WR? I went on the TS website and ordered what they said were the required parts at almost$200, and when I got them I couldn't tell the old sub frame reducers from the new ones. Also not sure what a MT limiter strap slide stop washer is for. Or where it goes. Waiting for a call back from TS now, but I haven't had much luck reaching anyone there lately.
