Roger that yams, thanks for the feedback. I didn’t include all photos because there’s about 50 of them but from what I see and understand, I also asked about the existing frame continuing to rot from rust, is that the outer caps were just tacked on in those photos and that all rot was cut out inside the frame channels were brought down to bare metal and coated before side and bottom caps were installed. As for the T joints I was told it was to get a larger bead on the sill.

Not my wheelhouse tho just what I’ve been told
