which bracket for 23cc?

[Rlbol]

So I finally found my boat. It is a 84 23 cc.
I will post pictures once i figure out how!
So it is a 23cc originaly an I/O but has been converted to a bracketed outboard with 250 yamaha. Boat runs great but the bracket on there now is basicly a u shape and it is open on the top. I am going to replace that bracket with a full bracket and platform. It needs to have a ladder to make it easier to get in and out for the kids. So my question is which one? I have seen the armstrong ones but that is about it. which one will go best with the hull as well as the motor? it is a 2000 250 yamaha.
Thanks!
