ORIGINAL early GT40 MKI louvered panel

[Rex]

Want to buy or borrow an ORIGINAL early GT40 MKI louvered panel (mounts on the tail panel on each side of the exh outlet). Looking for the EARLY style panel with 9-10 vertical rows of 1" long miniature louvers, NOT the later style. Will pay $300 to buy or borrow an original panel, or the name of a source for the proper louvered aluminum material. Thanks.
