I finally gave up on the idea of utilizing the brushed aluminum tambour product. The manufacturer assured me that it was entirely compatible with the plastic track mechanisms, but I just got a little leary of "blazing a new trail".
After talking with local distributors and checking with three different catalog/Internet sources, I decided to go with Tape-Ease. Rather than try a laminate that likely wouldn't match the original off-white material, I chose their 3/16" birch veneer tambour with the 1/2" slat width. The vendor who is doing my restoration work thought that it might be easier to get something approximating original appearance by utilizing a natural wood and either staining or pickling it to attain a near match. I also ordered some of their track and guide assemblies to replace some that were damaged/warn on my coach. The page where I found the tambour that I ordered is:

I just received an e-mail from the vendor who is doing my restoration work, and the tambour had just arrived. I am just holding my breath until I hear whether the product works as well hoped.
