Are Leland 7910 and 7920 Pin Boxes the Same Except for the Length

Question:

Does the Leland 7920 and Leland 7910 interchange, and if so, is there a difference other then the shorter measurement from pin center to the front hole center?

The Leland 7910 and 7920 pin boxes are very similar with the difference being the length of each. The 7920 is longer, like you said, measuring 21 inches from the first row of bolt holes to the center of the king pin whereas the 7910 is 9 inches. I have included a link to the pin box options for the Leland pin boxes.
