Dredging up this old thread
I made a mistake and assumed that the first aid box 53107044958 fit all E46's. So I bought it along with the mounting bracket 52107 045018. And bought 2 #12 x 3/4" machine screws. 2 things happened on the install
1) the bracket mounted easily, but now the thigh support on the Sport seats won't move. I'm guessing those screw are too long
2) the first aid box won't slide in to the bracket because it hits the metal bar that goes across the underside of the seat
I've now read that that bar only exists on the convertibles, and if I'd done my research on Realoem I'd have found that the convertible has a different box 52107008620, and the correct BMW screw is 07149169302 M6 x 12 (and looks much shorter).
Only good news is I have the right bracket
But before I order the screws, I'm not finding a source for that convertible first aid box 52107008620. Does anyone have any ideas where to find it? The first aid box I bought in error is for coupes and sedans, and can be found everywhere......
