r33 taillight bulbs please help

im doing a skyline taillight conversion with the r33 4 door models but i have a couple blown bulbs and i cant find them anywhere here in the states i was hoping the people with more accesibility could help me find where to get them

As far as I know normal brake and turn signal lights work.

ive tried normal push in bulbs but the base is to small so they pop out of the harness and the bulbs themselves are to big to slide into the light

I'll see what I can find out.
