Thanks for reaching out Marshall. Unfortunately, the Curt Flex Air 5th Wheel Pin Box - Lippert 1621 # LC328492 will not be a direct replacement for your existing pin box. If you have a Lippert Turning Point pin box, it uses a proprietary mounting bolt pattern that's different from the standard Lippert 1621 pattern. The mounting hole spacing is significantly different, so the # LC328492 won't bolt directly into your existing pin box mounting wings. I've included a couple of photos below showing the differences between the two mounting patterns so you can see why they aren't interchangeable.
At this time, the only direct replacement options we carry for the Lippert Turning Point are gooseneck style pin box conversions, such as the Gen-Y Hitch Shock Absorbing 5th Wheel-to-Gooseneck Pin Box - Lippert Turning Point # GY48GR. This would allow you to replace your existing Turning Point with a shock absorbing gooseneck connection. However, it would also mean switching from your fifth wheel hitch to a gooseneck ball and safety chain setup in the bed of your truck.
What's making you consider replacing your Turning Point pin box? If you're mainly looking to improve ride quality or reduce chucking while towing, there may be some other upgrades worth considering that wouldn't require changing your entire hitch setup.

Ride quality. I have an auto slide 5th hitch so Goose is not an option. Already planning the Roadmaster Comfort ride leaf upgrade. Man, that's unfortunate.
