Tight ps gearbox??

Ok I just swapped out a gear box on my dads 73 cuda and for some reason it seems tight so tight that the ps pump wines . So I thought well that pump is goin out as well so I swap out the pump with a new one and its the same problem.

The original gear box looked like this one Screenshot_20210727-212713_Chrome.jpg

The new one that we got from the local car quest looks like this

It there a way to adjust this ? Or do we gotta take this thing out and get another one?
