Rudders

I'm looking to get a rudder for my prowler big game . any suggestions on where to get one . I seen a couple on amazon but wasn't sure if it would fit or not .  on the ocean kayak site they were not clear on what fit what they used abbreviations . doe PBG stand for prowler big game . I'm assuming it does . also it had an option for pre 2013 and post 2013 . how can I tell when mine was made

I would give Ocean Kayak a call and give them the serial no. and I'm sure they can help you out with what year your yak is and what fits it..
