Does anyone know the difference between the LWB seats and the standard Series 3 seats? I have an 82 LWB and I need to replace the seat pads both bottom and back pads. The "deluxe" seats look way more comfortable than the issue seats in the lwb's. Do the deluxe seats have the tabs like the LWB seats or do they mount differently due to not needing to lift the seats bottoms for petrol?

Thanks!!
