Does anyone have pictures, dimensions, or a description of the recaro SE bracket for the 320i. I was rear ended and the factory seat bases tore away from the floor and I will be rebuilding them to be stronger than before; I'm sure I'm not the only one who has had seat rail bolts pull out of the bases. I want to install recaro se seats but 400 for brackets seems extreme. I would like to make my own but want to know what I'm getting into before I buy the seats. I'm sure anything I build will be much stronger than the factory base anyway. Thanks
