Rinker 234 captiva parts

Hi all Brent here from Auckland New Zealand well recently I took the plunge and bought a Rinker 234 Captiva and its used in fairly open waters and I am pleased to say it handles the copy sea quite well despite what is said about these American boats.
Guys I'm looking to exstend the boarding platform for fishing and I have seen one on line can anyone help me track one down?
Cheers
One happy kiwi Rinker owner
