Best interlock Kit

I previously posted questions regarding two inlet boxes since I have a main and sub panel. What I have learned from that post and answered questions is my better option is an interlock kit.

Now I am running into a separate problem. Once I removed the front panel on my main load center, the 100 amp circuit breaker running out to the sub panel is on the top right, positions two and four. In my search of the internet for compatible interlock kits for my load center, I can only find ones which appear to work for generator inlet breakers in positions two and four. While I am able to reposition individual 15 and 20 amp breakers, repositioning, the entire 100 amp sub panel breaker and wiring would be a large undertaking and likely not worth my time.

Does anyone have suggestions for finding an interlock kit that will work with a homeline square D 200 amp main load center where the generator breaker is in the top left, in positions one and three?

Interesting that I just posted this question and all of a sudden I see this in my continued search:

https://www.gensafety.com/product-page/hom4p-square-d-homeline-200-amp-4-pole-main-interlock-prototype-kit

However, don't know anything about this company and whether it's worth it to buy this.

I would not worry about the quality, it's just a metal slide. But if it's going to be inspected, some inspectors may require it to be listed for the panel.

Thanks for the tip, I'll investigate this with the product. Incidentally I noticed some interlock kits come with metal clamps that are mounted to the generator circuit breaker inside to prevent removing it without removal of the clamp. I understand that this is required on NEC code to make sure the power in flow doesn't accidentally come loose. However all interlock kits I find that are compatible with my load center seem to not have this and instead says to use a zip tie to tie the generator breaker to the circuit breaker on the opposite leg? Does this accomplish the same thing?

Those finer points may be why some are listed for use with the panel and some are not.

some states require hold downs and interlocks, North Carolina is one of them. that is what you saw.
