Borgeson Mopar Steering Shaft Coupler

Borgeson Mopar Steering Shaft Coupler

I'm looking at picking this coupler up to replace the horrid stock coupler on my 68 Dart. The description on the Borgeson website states that it fits the stock column with the Borgeson PS box. Will this coupler still work with a stock PS box? I'm assuming the Borgeson box is the same as the stock or reman'd units from A1 Cardone for example?

Thanks
