race cougar just talked about this in his thread, this is the part that is available for 64-66 trucks, however the bottom corner is not correct, it is a replacement piece, not a "restoration" piece... meaning that it will work, and appear correct for the most part, except for us eagle eye purists!
before today I did not know that the patch panel was stamped different.... I wonder what the inside of the reproduction door looks like?
here is the thread, post # 330, page 14
