Gen 5 Camaro Drivetrain Tech - Camaro SS Tremec TR6060/M10 Output Flange Question

Has anyone swapped out/changed the fixed driveshaft mounting flange/yoke on the back of the Tremec TR6060 6-speed transmission that come in 2010 Camaros? I will be putting in a custom driveshaft in my swap project and would like to find a flange or bolt-on yoke that will bolt directly up to the TR6060 and allow me to replace the flex coupler.

If someone knows a manufacturer or P/N for a compatible part, please let me know.

As a follow up to my own posting:

It took a lot of phone calls and internet searches, but I found a company in Phoenix that custom fabricated a flange that fit the back of the TR6060.

The company is: Driveshaft Superstore.
