I don't know of any companies that sell a york bracket for a 235. Kilby Enterprises has loads of good info on yorks, though, so you might contact them. I ran mine of the PTO, which works fine, but you have to be stopped to engage the PTO. Running it off the engine is definately a better option, so you can have air on the fly.
