So your Keystone Montana 3670rl will either have a Lippert 1116 pin box or the 1621. Count the amount of bolts that are on each side of the pin box. If it's 6 then you have the 1621 and you need the part # RP34FR.

If instead it's 9 you need the part # RP77FR and you have the 1116.

You have 6 which means you have a 1621 and the correct Sidewinder is # RP34FR.

I can’t seem to find the right info in any of the Q&A for the sidewinder that I am looking for. I just got a 2020 fuzion impact RV and I want to switch to a sidewinder. The factory pin box is a lippert rotaflex 19K but I can’t find a part number on it. It has 9 holes that are spaced 4.5” apart side to side and 2.5” apart top to bottom. Would the sidewinder elite 19K work or the regular 19K sidewinder? Does Reese make a 5th airborne sidewinder that is 19K? Thanks

Do you see any numbers printed on the pin box itself that would refer to a specific model? If not, can you tell me the serial number stamped onto the king pin?
