Bumping this thread back up since I'm planning on doing this in the foreseeable future. Though i'm concerned.... you had all those issues with med-duty springs?
I want to clarify something here:
OME rates the springs as light duty and medium duty for XK's, and the SAME springs as medium and heavy duty for WK's. We (onlline XK/WK community) generally refer to the OME springs in terms of the WK designations of medium and heavy duty.
Thus my question: Did you have issues with the XK medium duty springs, which are actually the WK heavy duty springs?
