1968 26 Overlander rear compartment door

Hello, I am new to this forum, I have recently purchased 2 1968 26 foot Overlanders. Both are pretty much in the same shape. Both interiors still stock and both are missing the rear exterior compartment doors. If I had one for a pattern that would be no problem to fabricate. But alas I do not. Is there anyone out there that has a drawing or such that a person could make a couple reproductions? Or does anyone sell them? I know that they can be had for around $275 but that seems a little steep. Thanks Don
