I am in need of a front right passengers seat belt for a 2003 R53 S. (made in 2002) RealOEM shows seat belt parts numbers that apply to up to 10/03 and after 10/03. Mine ends in 7073129 - using air bag 82402. Looking at used belts on Ebay I see very few with the proper part number and air bag number but they are high in price. I also see many more that state they are compatible with 02-06 models but their label show they are for a different air bag. Might anyone know if they are interchangeable.
