Help, i tried to install the recently purchase replacment HID bulbs. The stock bi-xeon has some sort a of Metal square bracket at the bottom of the stock bi-xeon. The replace bulbs are slightly different in the sence that they dont have this once peice "metal bottom bracket. This is quite the different replacment, on my e46 m3 it was simple plug and play ... anyone lend a little light on this before i have to spend extra un pleasent $$$

Any help will be greatly appreciated
