i got 3rd gen. integra seats, they didnt fit at all, i drill out the welds from the factory seats and bolted them back into place, then cut off the ones from the teg seats and then placed the seat into place on the factory mounts, tack welded them, then pulled it all out and apart and welded it all up and bolted back in
i know they dont match right now but they will be re-wrapped when its time to do the interior
