Comparing Borgeson's power steering box to the mopar OEM box

Aren't they an adaptation of the power steering box from some flavor of jeep?

I think they start with a 2000's Jeep box and machine some of it away, and then weld on a bracket for Mopars. Input and/or output shaft is modified too.

I put a Borgeson on my Dart and am happy with it! (It was also nice that the factory was about a mile from my house. No longer the case.)
