Raymarine ST4000 free parts
I just upgraded to an X-5 with I70 control head. My old ST4000 was in working condition and I salvaged the compass and control head/computer. However, the wheel drive did not survive the removal process in tact. I would be willing to give you my old parts if you pay for the postage. Let me know if you are interested.
I am new to this so it wont let me post my email yet.
