Durst 6x7 negative carrier for the Durst CLS450

Did Durst ever make a 6x7 or 6x9 negative carrier for the CLS 450 model? I've search everywhere but I can't seem to find one... not even on eBay.

The CLS450 is just the colour head. It mounts on a diffusion box holder and then to the enlarger itself. I have both Durst 6x7 and 6x9 holders that fit the Ce1000, Omega holders will fit it as well.
