Here is the data for a JD 3038
Hydraulics:
Type: open center
Capacity: 5.5 gal [20.8 L]
Pressure: 2500 psi [172.4 bar]
Pump flow: 5.3 gpm [20.1 lpm]
Total flow: 9.3 gpm [35.2 lpm]
Steering flow: 4.0 gpm [15.1 lpm]
Steering press.: 1500 psi [103.4 bar]
So if the Land Pride kit is for an open center valve, then it could work.
Can you show pictures and describe what you have?
