Borgeson/Bergman Steering box kit

Hi,
Has anyone used the direct fit no modification Bergman auto craft coupler kit and Borgeson p/s box in their Dart ?

It's a bit pricey but I'm not happy with the new rebuilt p/s box I had installed in my 72 Swinger.

Best vender to buy the complete kit from ?

Your experience with install and end results....

Thanx Kevin
