I think so too. It is the one piece looking seat cushion that I can't find a model for. As you can see the Recaro base doesn't play well with a GM power base. I got two bolts to work at the rear rail. I had to add the front cross member just to have something to bolt to the power base. I then welded it to the side rails to make a four sided square base. Then I could bolt it securely. The tiny bolts that attach the seat to the base are a PITA too. Once it is all said and done it works fine, but is heavy as hell.the pic above has me thinking LS-B
