9012 bulb will not fit

having received 2 9012 toshiba HIR bulbs and removed the headlamp on my 1995 UK right hand drive 355 i can confirm that there is no possibility of putting the toshibas in......maybe it's because my 355 is a UK model........because the bulb just pulls out of its grey molded socket which is permanently attached to the headlight casing........there are no tabs that attach the holder as in the toshiba............everyone told me that the fit is easy by cutting part of one of the toshiba tabs but it is a completely different type of housing I have on my car.........any comments from anyone about this?..........are the uk headlamps so different to the american ones???

 

here is a photo of my light housing................the toshiba bulb cannot fit??????.....what's this about?.........does my housing look strange or normal???
