Mystery Aveo Sway Bar Bushes

Hoping someone knows what sway bar bushes are on my car!!! The sway bar bushes on my car (2013 Aveo 1.2) are not the ones listed for it. My bushes are twice the size, have a hard plastic base, split at the bottom, have two ribs as opposed to one central rib, and have an oval hole to accept the bar rather than a round one. Though my bar is round. The listed bush doesn't come close to closing around my sway bar and wouldn't come close to meeting the bracket when in place.

The auto parts store has checked and double checked their databases to find it, but there's no other sway bar bush listed for my car.

Hoping someone can help as I started with the bush that was sound before realising the new bushes weren't right, and after hours of trying to force the bracket back over the old bush I ended up having to take a hacksaw to the sides of the hard plastic base in order to get the bracket back on. So now I have two dodgy bushes!!!
