This work is based on $r'$ images and long-slit spectra obtained with the Gemini Multi-Object Spectrograph at the Gemini South Telescope. The luminosity ratio between the main (AM\\,2058A) and secondary (AM\\,2058B) components of the first pair is a factor of $\\sim$ 5, while for the other pair, the main (AM\\,1228A) component is 20 times more luminous than the secondary (AM\\,1228B). The four galaxies have pseudo-bulges, with a S\\'ersic index $n<2$.
