Cal 27 window frames

New to the group, what a great find for me! I have a 1971 Cal 27 pop top, and I need to replace the port and sb exterior window frames. can anyone point me in the right direction or is this another item that i am going to have to have created? what about a source for interior teak or mahogany window frames? i feel a lot better about working with wood than i do aluminum. this is just the first of what i'm sure will be many postings as i work on my project. Again, so glad to find the group. Larry Delaney Everett, WA 1971 Cal 27 pop-top "Mad Duck"
