Hmm, we might. Our 80-106 is currently the only patio door track we sell. Now, this doesn't look precisely like yours, but I personally find it to be a very versatile track and I've used it in all manner of patio doors regardless of brand. Plus, it's fully compatible with the 81-052 that I recommended, so I think it's at least worth considering. 

Look it over and see what you think; you'll note that it's a little skinnier than most tracks, but this allows it to be adjusted in most threshold channel to find an optimal position. The video guide below will show you how it works.
