What you did is very impressive! My only concern is, will the seat airbag be able to deploy properly in a car it was not designed to deploy in. The narrow Bolt seat may be necessary for proper airbag deployment, for example. There probably needs to be sufficient space between the B piller and door, and the seat. Hopefully this is something you will never have to find out about.

My wife was t-boned in our 2018 Volt by a 1996 Buick Roadmaster station wagon, and both cars were totaled. I'm glad the side airbags worked as designed. Had GM put the wrong seat in the car, they may not have.

There is such little difference in space between the door and seat, I can't imagine it making any difference. Airbags aren't even designed by the car manufacturers. They are third party and the same brand is used in all sorts of different vehicles. I'm sure that the exact same airbag would also be used in other cars where it's in a location that's 1/2 an inch different.

You are probably correct that it won't matter.

The Bolt was crash tested with the seats designed for the Bolt, not Volt seats. We don't know how it would crash test with Volt seats.

The angle of airbag deployment, the timing, etc are all specific to the Bolt. The way the seat airbag works in conjunction with the side air curtain is specific to the Bolt. Interior shape and dimensions are different between the two cars. It's unknown if a Volt seat airbag will deploy properly in a Bolt interior. Personally, I wouldn't take a chance, but it's impressive you got this to work.
