71 198 slant 3 on tree

I’m looking for the adapter to put up two barrel carburetor on this car ? I found them easy 15 years ago on my other darts I had . Now I can’t find anything .

I know people think it’s dumb , I don’t care I like my single barrels just fine but upping to a small 2bbl does help a bit and will allow me to do the smallest 2bbl efi on it
