Expert Reply:
The Lippert 1621 pin box is a very common pin box for your Heartland Landmark 5th wheel trailer. The Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter - Lippert 1621 - 20,000 lbs # RP85FR will work great to replace a Lippert 1621 pin box.
Since your numbers are difficult to decipher, I recommend measuring to confirm. I've attached an article to help you with the measurements to confirm a fit but will give you the measurements as well.
If you have the Lippert 1621 pin box, your measurements will be:
Horizontal---7-7/8 inches bolt center to bolt center
Vertical---2 inches bolt center to bolt center
Bolt Size is 5/8 inch
Bolt Head Size is 15/16 inch
There are 6 bolts per side
The front row of bolts to center of king pin is 17-3/4 inches
The back row of bolts to center of king pin is 25-5/8 inches
And finally the pin box measures 12 inches wide
