Here is a new radius cup attached to the floor with our solid rivets – a DEAD RINGER for the originals! The one place that I do change from the factpry is that I put a rivet into all 8 holes. At the factory, they only used one of the two side holes on each side, for a total of 6 rivets. – I think it was for clearance of the flanges on the seat dish panels above to make them siut flat. Screw it – when you have ripped these out of the floor in heavy driving with high HP, 8 is better!
