Need help locating this bracket

[daredvl22]

I posted this over at TC, but haven't recieved any replies. Does anyone know where to buy this bracket, or if anyone reporduces it? This is the bracket that attaches (glued essentially) on the inside of the rear quarter panel of a '67 Camaro. This piece attaches to the top of the rocker and inner structure of the rear door frame. My NOS quarters do not have these brackets.
