Hello Richard. Thanks for reaching out. I do have an option for you, but there is unfortunately no direct bolt-on gooseneck replacement for the Fabex 730 pin box.
The best option will be to use the Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box # GY38FR. In order to use this, you will have to drill a few holes in the brackets to match your trailer. As long as you only drill the necessary holes and do not drill a bunch of extra holes you will not void your warranty on the pin box. This kind of work is best done by a professional. Keep in mind you will also need the 1/4" filler shims # GY76FR.
Another option is the Ranch Hitch Universal 5th-Wheel-to-Gooseneck Coupler Adapter # AM3100 which will bolt on to your king pin and will allow you to connect to a gooseneck hitch. I generally try to avoid using this kind of adapter unless there is no other choice. If you are ok doing a bit of drilling, the # GY38FR goosebox will be the best option.

Hey Richard, how did things go with the Gen-Y gooseneck pin box on your Coachmen Catalina? Were the drilling steps manageable for your setup? Your update could make it easier for others working with a Fabex 730 pin box.
