Swapping out a leaky power steering box for a Firm Feel stage II unit. This one is the later 73'+ large spline with a new 1973 barracuda pitman arm. My question is what is any torque specks for installing the box, or can I just get away with just getting it tight and firm on there?

The car is a 1971 challenger with stock suspension, 15x8 wheels and disc brakes.
