Tiller to Pedestal Steering Conversion
What issue are you trying to solve with converting your First 235 to a wheel? If it is one of ease of steering because you cruise more than you race, a tiller pilot would be a much better investment. We had an Autohelm 2000 for our Beneteau First 325 and it worked great. You could take the helm when you wanted to experience the feel of sailing and flip to the pilot when you needed a break. The tiller pilots require no installation other than a 12 v. outlet and a bracket on the tiller and a mounted fitting for the removeable arm, all for about $800 if I''m not mistaken.
