The 9011 is an HIR bulb - a special incandescent with a coating to reflect some of the infrared back to the filament to make it brighter.
It is easily modified to drop into a 9005 socket as a high beam. I believe the low beam option is the 9012 as it has a black cap on the top. I do not think there is an HIR bulb with dual filament for a hi/low socket (9004, 9007, h4). Which 02 headlights do you have?
On the rotational alignment - if there were no locking tabs used on the washer that seats the projector to the headlamp housing - you might be able to insert a screwdriver into the bulb hole & rotate for the correct line up without opening the headlight.
I have quad mini h1's in my 05 and offset the throw issue with a pair of hella 500s
I would not recommend a bright fog light bulb as the mini h1 puts out a strong foreground & adding bright fogs will destroy your long range perception.
