Does anyone know the part number for the 4 bolts that hold down the black plastic cover for the electronic/DME box located behind the passenger side (right side) strut tower inside the engine compartment ? I nearly butchered one of these bolts when I recently changed to an EAT chip. Went to local Pacific BMW dealer in Glendale and they couldn’t come up with the right bolt for some reasons. The car is a US-Spec 91 E34 M5
