For sale is a complete Yacht Specialties (now Edson) tiller to wheel conversion kit. It includes all pulleys, pedestal w/ compass, mounting plates, hardware, etc. It is all in good working condition and is off my Yankee 30 which it worked well on. Selling because I converted back to tiller. The only thing that is slightly altered is the steering cable which I had to cut at the eye where it meets the mounting bracket by the rudder post. Likely it would be easier to run a new cable anyway which is cheap and size it to your boat. I also found a pdf of the original installation instructions online I can send you a link to.
How about $200 for it all. I'll ship it at your cost or come pick it up in New Orleans.
