Seat belt extenders

This site may earn commission on affiliate links.
I have 2 seat belt extenders, bought directly from http://seatbeltextenderpros.com out of my 2020 Model Y. They are the black 3” rigid ones designed for 2nd row window seats.

Selling them because I now have a 2022 and there was some change where they are not compatible. I do not know if they will work in a 2021.

Selling for $15 shipped each
Or $25 shipped, for both

I don’t have personal experience with a ‘21 model but comparing the extender I have on hand for the ‘20 and ‘22, the ‘22 is about 1/2” longer.

I do have an extra pair of extenders for a ‘22 if you’re interested. Below is a link to that posting.

Any way to verify if they work on a 22 Model 3?
These are the ones I have and don't work.

I don’t have a 22 Model 3 to check with but I took measurements of my 22 Model Y male end, which are in my attached pic for you to check with yours.

I also took a pic of the difference in extenders and there are little notches on older version, which prevent the new buckle from going all the way in. It seems that’s the reason the old one won’t work with the new car. The new extender doesn’t have those notches.

Attached is a photo of the belt fully inserted but not locked in. The buckle does look different on yours compared to mine. I have a feeling the one with the notches will work for me. If you can somehow verify it fits the 22 M3, I would gladly take them.
