What's the 1/2" t-molding for? Original had 3/4" next to the CPs from my recollection...I don't own an original anymore. I believe you had to remake those parts? Did you remake them with 1/2" material? I can give you a small length of 3/4" for shipping.
Have a link for the Rockler hinge you are talking about. I know I have some hinges, probably not what you are talking about but you never know.
