Is the truck one metric? What do they look like where the line threads in. What are you trying to do?

Just wondering what the difference is
Wondering if there is an advantage to running one or other

What are you trying to accomplish? The part you show looks to be the pump's high pressure relief valve - flow control valve. Its specific to the pump volume - pressure capabilities in relation to the steering box volume - pressure needs. IMO....do not arbitrarily interchange them....

I am going to hydroboost brakes and just want to make sure I have adequate pressure with stock pump

IOM....you would need to verify your pump's capabilities (FSM specs ?) with your proposed hydro boost system supplier and ask for written confirmation of acceptability.

How did you do that

How did you do that

If I recall correctly, I brazed the output orifice closed and drilled to a smaller size. I used instructions from Erenberg at Mopar Action Magazine, where I read an article detailing such a procedure. You can probably search and find it.
