We can tell you how to determine the correct Gen-Y 5th wheel-to-gooseneck that will fit your 2021 Fuzion 429 toy hauler, but that will depend on the current model of pin box you have now, and we don't have a way of knowing what is currently on it. So to determine the correct option, you will need to check your pin box for a sticker or placard that will have the pin box number on it, or you can use the article I linked below on choosing your pin box, which tells you how to measure your pin box to determine which one you have.

The one you asked about, the Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box # GY56FR is a replacement for a Lippert 1621 or 1621HD, though it has a capacity of up to 18,000 lbs towing and is for pin weights between 1,000 lbs and 2,000 lbs.

Based on the specs I saw for a 2021 Fuzion 429, it has a GVWR of 20,000 lbs and an empty pin weight (hitch weight) of 3,555 lbs. Based on that you will need a different option than the # GY56FR; so if you do have a Lippert 1621 or 1621 HD, you would need the Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box # GY38FR.

The # GY38FR has a 25,000 lb capacity and is for pin weights between 2,000 lbs and 4,500 lbs. If you let me know what model your pin box is I can find the right Gen-Y for you, or I have added a link below to our entire selection for you.
