I will be upgrading my NAA hyds soon by modifying the top cover option plate so that I can tap pressure down near the relief valve test port, then run thru a open center valve, then return oil back to the option cover thru a port added to it.. 3pt will still work, and I can now run my loader with a regular valve control vs chaining down the 3pt and using the lift control as the loader control.
