Pump it down TRW pump?
For the best advice I would call Bergman Auto Craft. He’s very knowledgeable and easy to talk to.
On my ‘67 Barracuda I called Turn One Steering and they suggested a flow restriction valve, such this for my Saginaw pump. Not sure if it is what I bought though.
Turn One Steering - Steering Products
The OP may want to call both.
