Generator Interlock Kit - Which One?

Bought a new house recently and have been going through the panel identifying all the breakers.. making great progress but now I'm on to planning for the generator.

I plan on putting in a basic reliance 30amp inlet box outside to plug the generator in to but I'm having a hard time figuring out what interlock to get.

The panel is an older Square D but it has 200amp 4-pole vertical breaker main with the individual breakers being horizontal. I'm okay with moving breakers around-- have plenty of room. Just looking for the appropriate interlock to protect the 4pole main from the 2pol/30am generator breaker.

Attached are pictures. Any help or suggestions would be greatly appreciated.

I don't know if you have looked at, but you might check there. They have an option of sending in your panel measurements, and they will create a custom kit to match it, if your panel is not listed in one of the brands. I've also read that you can get interlock kits directly from the manufacturer, but I don't know if Square D does this.

Square D does make interlocks and they usually cost much less than interlockkit.

You need the model numbers of your panel.
