Tony, if you are referring to the swim step it is a martin marine step. It is made to fit the montauk. You can find them on ebay or contact them direct. I believe it is martinmarine.com. Expensive but a great step
Thanks for the info, I will give them a call. I have two projects on the go.. my Montauk, like yours and a 89 Revenge WT. I have just finished the teak and everything should be ready to launch shortly. I will post some pictures.
Where did you get the swim grid as I am looking for one for my boat.
