Question:
Can you send me specifications and differences on the GY73FR and the GY66FR gooseneck adaptors? I have a 2021Montana with a Lippert 1116.

The only difference between the Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box - Lippert 1621/1621 HD - Auto Latch - 25K # GY66FR and # GY73FR for the 1116/1716 pin box is that they have a different bolt pattern.
The bolt pattern for the 1621/1621HD is 7-7/8" between the horizontal holes, and 2" between the vertical holes, and the 1116/1716 is 8-3/4" between the horizontal holes, and 2-1/2" between the vertical holes.
Since your 2021 Keystone Montana has the 1116 pin box you will need to use the # GY73FR.
I included a video of the # GY73FR for you to take a look at.
