AT Controller 300 is under $3400 last time I knew. Hydraulic hoses and labor I'm still thinking it's not close to $20k. $10k might do it depending on how easy or hard the machine is to do. Maybe more or less if you hire it done or do it yourself.
No idea what kind of steering the Apache has but here's the flow chart for the JD AT Controller 300
