Where to find out of production replacement panels?

Hi all,
As soon as I can find a free weekend to go pick it up, I'm going to be starting a refurb project on an old single wheel teardrop that I'm picking up to tow behind my VW bus. The trailer has some minor rot on the exterior siding (probably from leaning against the ground for 25 years), so I have a panel or two to replace. But in my searching I haven't found any matching siding patterns. What's on it appears to be a 3/4" mesa pattern (or at least that's the closest pattern I found), but all I can find are 1" and 2".... So is there a good place to look for oddball siding like this, or do I need to have the panels custom made?
Thanks all.
