Hey Chris! Do you need that full 20k capacity? Do you have disc or drum brakes? I recommend the following based on brake type:
-Demco Hydraulic Brake Actuator w/ Drop - Drum - Zinc - 2-5/16" Ball - 20,000 lbs # DM8204011
-Demco Hydraulic Brake Actuator w/ Drop and Electric Lockout - Disc - Zinc - 2-5/16" Ball - 20K # DM8204311
Both are designed to fit a 3" wide tongue and use a 2-5/16" ball with the same capacity you have now. If a lower capacity will work let me know in the comments below. There are lower rated options that could save you some money.
