My riser was broke on my 235 so I took one off a 250 and put it on my 235. works great. I had to grind the weld to get it out of the 250. Then grind it to fit the 235, minimal. I stuffed the shaft in with care to get alignment right and tack welded it in place. I checked it with a propane torch. It moved when heated. Easy as standing a shoestring on end. But couldn't find all the parts any where.
