There is only one type of fenton available, so don't worry about it. It will fit the 235. For the exhaust, the fentons are designed so that the one side can reuse the stock exhaust system (center dump type, not rear dump) the other side would need to be slightly customized. If you can't find a shop to help you, do you have a MIG welder? if so you could piece together your own system. JC Whitney has different types of elbows, etc.. available. I have never seen pre-made systems available, I would think it wouldn't be cost effective due to low volume and the many variations needed to cover all situations.
