thanks, they did give me the M3 headlight adjustment arm (actually I bought it separately).
For the stock 3 series setup, the stock headlight adjustment arm connects to a small bracket and the bracket clips to the stock wishbone arm.
For the M3 wishbone arm, there is a small eyelet on the M3 wishbone arm, and I've temporarily fastened the new M3 headlight adjustment arm to the M3 wishbone arm eyelet with a small nut. I'm wondering if I did this correctly or if there's a different way of attaching.
