There should be a sticker or a stamping on the OEM pin box of the trailer that will list the pin box number that is on the trailer.
Once you figure out which pin box you have you can check the FAQ I attached that has a chart that shows the correct Sidewinder to get based on which pin box you have.
If you cannot find the number you can use the measurements of the bolt holes of the pin box to determine which one you have. I attached an FAQ on how to do this for you to check out also.
The part # ST400-5AS16K you are interested in would be the correct Sidewinder for if you have a Leland 7910, 7920 or 7921.
