Seeking TABE 11/12 and CASAS one-to-one correlation for scoring

We currently use TABE 11/12 for ABE and ASE, while we use CASAS for our ESL/ELL students. We'd like to switch completely to CASAS, but two of our community partners want us to have a one-to-one score correlation between CASAS and TABE. I have plenty of the charts that show correlated RANGES, but not specific one-to-one scores. CASAS didn't have anything like that, but I'm wondering if anyone here knows of a resource. Thanks!
