The cruise buttons, SWC'c etc. and mounts are very different.
The airbag connectors are different. Dual vs single stage.
Better off using a preFL STi, PROVA, DAMD, K2 or GTspec steering wheel.
The aftermarket items all feature a smaller diameter rim.
Visually, the primary identifier is preFL = 1 tab below the hub for attaching the cruise etc. controls vs. 2 tabs on postFL.
Airbag delete QR hubs are available for e.g. track cars.
Another option is to get your steering wheel shaved for slightly less diameter, repadded and rewrapped by an automotive trimmer or DIY that.
